| 1 | Isotopic evidence of TSR origin for natural gas bearing high H_2S contents within the Feixianguan Formation of the northeastern Sichuan Basin, southwestern China显示文摘The northeastern area of Sichuan Basin, southwestern China, is the area with the maximal reserve of natural gas containing higher hydrogen sulphide (H2S) that has been found among the petroliferous basins of China, with the proven and controlled gas reserve of more than 200 billion cubic meters. These gas pools, with higher H2S contents averaging 9%, some 17%, are mainly distributed on structural belts of Dukouhe, Tieshanpo, Luojiazhai, Puguang, etc., while the oolitic-shoal dolomite of the Triassic Feixianguan Fm. (T1f) is the reservoir. Although many scholars regard the plentiful accumulation of H2S within the deep carbonate reservoir as the re-sult of Thermochemical Sulfate Reduction (TSR), however, the process of TSR as well as its residual geological and geochemical evidence is still not quite clear. Based on the carbon iso-topic analysis of carbonate strata and secondary calcite, etc., together with the analysis of sulfur isotopes within H2S, sulphur, gypsum, iron pyrites, etc., as well as other aspects including the natural gas composition, carbon isotopes of hydrocarbons reservoir petrology, etc., it has been proved that the above natural gas is a product of TSR. The H2S, sulphur and calcite result from the participation of TSR reactions by hydrocarbon gas. During the process for hydrocarbons be-ing consumed due to TSR, the carbons within the hydrocarbon gas participate in the reactions and finally are transferred into the secondary calcite, and become the carbon source of secon-dary calcite, consequently causing the carbon isotopes of the secondary calcite to be lower (?18.2‰). As for both the intermediate product of TSR, i.e. sulfur, and its final products, i.e. H2S and iron pyrites, their sulfur elements are all sourced from the sulfate within the Feixianguan Fm. During the fractional processes of sulfur isotopes, the bond energy leads to the 32S being re-leased firstly, and the earlier it is released, the lower δ 34S values for the generated sulphide (H2S) or sulfur will be. However, for the anhydrite that participates in reactions, the higher the reaction degree, the more 32S is released, while the less 32S remains and the more δ 34S is increased. The testing results have proved the process of the dynamic fractionation of sulfur isotopes. | ZHU Guangyou ZHANG Shuichang LIANG Yingbo DAI Jinxing LI Jian | 2005 | Science China Earth Sciences2005，48，11： | 58 |
| 2 | Discussion of gas enrichment mechanism and natural gas origin in marine sedimentary basin,China显示文摘There are abundant natural gas resources in Chinese marine sedimentary basin. The exploration hot shots of natural gas are the Palaeozoic marine strata here in recent years, and several large scale gas fields have been discovered. Chinese Palaeozoic high-post matured and coal measure hydrocarbon source rocks are mainly prone to gas generation in the present. This research considered that gas source rocks and TSR are the key cause of gas enrichment of marine strata. High-quality argillaceous and coal measure hydrocarbon rocks are distributed widely in the Palaeozoic marine strata, which have been in highly matured phase in the present. The argillaceous source rock generally contains various sulfates that could accelerate crude oil cracking to gas for TSR occurrence, and coal measure source rock mainly generates gas, so Chinese marine basin gives priority to accumulating gas. Marine strata have not founded oil reservoirs in the Sichuan Basin and Ordos Basin, and they consist mainly of dry gas. Marine natural gases are the mixed gases of oil cracking gas and coal-formed gas in a general way, oil cracking gases contain usually some H2S and CO2. Hydrocarbon carbon isotopes are very complicated, and methane and ethane isotopic values bear apparent reversal caused by thermal evolution and mixing among different genetic types of natural gas. Coal-formed gases are the main component of Chinese marine natural gas. The Upper Permian of the Sichuan Basin and the Carboniferous-Permian of the Ordos Basin coal measure hydrocarbon source rock present large hydrocarbon generation potential, which are the prospecting highlight of marine natural gas hereafter. Oil cracking gas exploration will be paid much attention to in the Tarim Basin because of the lack of coal measure hydrocarbon source rock. | ZHU GuangYou ZHAO WenZhi ZHANG ShuiChang LIANG YingBo WANG ZhengJun | 2007 | Chinese Science Bulletin2007，52，A01： | 41 |
| 3 | Origins of High H_2S-bearing Natural Gas in China显示文摘Natural gas containing hydrogen sulphide (H2S) has been found in several petroliferous basins in China, such as the Sichuan Basin, Bohai Bay Basin, Ordos Basin, Tarim Basin, etc. Natural gas with higher H2S contents (H2S >5 % mol.) is mostly distributed in both the gas reservoirs of Dukouhe, Luojiazhai, Puguang and Tieshanpo, which belong to the Triassic Feixianguan Formation in the northeastern Sichuan Basin and those of the Kongdian-Shahejie formations in the northeastern Jinxian Sag of the Jizhong Depression, Bohai Bay Basin. In the Sichuan Basin, the H2S contents of natural gas average over 9% and some can be 17 %, while those of the Bohai Bay Basin range from 40 % to 92 %, being then one of the gas reservoirs with the highest H2S contents in the world. Based on detailed observation and sample analysis results of a total 5000 m of core from over 70 wells in the above-mentioned two basins, especially sulfur isotopic analysis of gypsum, brimstone, pyrite and natural gas, also with integrated study of the geochemical characteristics of hydrocarbons, it is thought that the natural gas with high H2S contents resulted from thermochemical sulfate reduction (TSR) reactions. Among them, the natural gas in the Feixianguan Formation resulted from TSR reactions participated by hydrocarbon gas, while that in the Zhaolanzhuang of the Jinxian Sag being the product of TSR participated by crude oil. During the consumption process of hydrocarbons due to TSR, the heavy hydrocarbons were apt to react with sulfate, which accordingly resulted in the dry coefficient of natural gas increasing and the carbon isotopes becoming heavier. | ZHU Guangyou ZHANG Shuichang LIANG Yingbo DAI Jinxing LI Jian | 2005 | Acta Geologica Sinica(English Edition)2005，79，5： | 36 |
| 4 | Prognostic nutritional index is an independent prognostic factor for gastric cancer patients with peritoneal dissemination显示文摘Objective: The predictive and prognostic role of prognostic nutritional index(PNI) in gastric cancer patients with peritoneal dissemination remains unclear. This study aims to explore the role of the PNI in predicting outcomes of gastric cancer patients with peritoneal dissemination.Methods: A total of 660 patients diagnosed with gastric adenocarcinoma with peritoneal metastasis between January 2000 and April 2014 at Sun Yat-sen University Cancer Center and the Sixth Affiliated Hospital of Sun Yatsen University were retrospectively analyzed. The clinicopathologic characteristics and clinical outcomes of patients with peritoneal dissemination were analyzed.Results: Compared with PNI-high group, PNI-low group was correlated with advanced age(P=0.036), worse performance status(P<0.001), higher frequency of ascites(P<0.001) and higher frequency of multisite distant metastasis(P<0.001). Kaplan-Meier survival curves showed that PNI-high group had a significantly longer median overall survival than PNI-low group(13.13 vs. 9.03 months, P<0.001). Multivariate survival analysis revealed that Borrmann type IV(P=0.014), presence of ascites(P=0.017) and lower PNI(P=0.041) were independent poor prognostic factors, and palliative surgery(P<0.001) and first-line chemotherapy(P<0.001) were good prognostic factors. For patients receiving palliative surgery, the postoperative morbidity rates in the PNI-low group and PNIhigh group were 9.1% and 9.9%, respectively(P=0.797). The postoperative mortality rate was not significantly different between PNI-low and PNI-high groups(2.3% vs. 0.9%, P=0.362).Conclusions: PNI is a useful and practical tool for evaluating the nutritional status of gastric cancer patients with peritoneal dissemination, and is an independent prognostic factor for these patients. | Runcong Nie Shuqiang Yuan Shi Chen Xiaojiang Chen Yongming Chen Baoyan Zhu Haibo Qiu Zhiwei Zhou Junsheng Peng Yingbo Chen | 2016 | Chinese Journal of Cancer Research2016，28，6： | 19 |
| 5 | The controlling factors and distribution prediction of H_2S formation in marine carbonate gas reservoir,China显示文摘Generally, there are some anhydrites in carbonate reservoir, as H2S is also familiar in carbonate oil and gas reservoirs. Nowadays, natural gas with high H2S concentration is usually considered as TSR origin, so there is close relationship between H2S and anhydrite. On the contrary, some carbonate rocks with anhydrite do not contain H2S. Recently, researches show that H2S is only a necessary condition of H2S formation. The reservoir porosity, sulfate ion content within formation water, reservoir temperature, oil/gas and water interface, hydrocarbon and some elements of reservoir rock have great controlling effects on the TSR occurrence. TSR deoxidizes hydrocarbon into the acidic gas such as H2S and CO2, and the H2S formation is controlled by TSR occurrence, so the relationship among reaction room, the contact chance of sulfate ion and hydrocarbon, the reservoir temperature has great influence on the TSR reaction. H2S has relatively active chemical quality, so it is still controlled by the content of heavy metal ion. Good conditions of TSR reaction and H2S preservation are the prerequisite of H2S distribution prediction. This paper builds a predictive model based on the characteristic of natural gas reservoir with high H2S-bearing. In the porosity reservoir with anhydrite, the formation water is rich in sulfate and poor in heavy metal ion. Oil and gas fill and accumulate in the gas reservoir with good preservation conditions, and they suffered high temperature later, which indicates the profitable area of natural gas with high H2S-bearing. | ZHU GuangYou ZHANG ShuiChang LIANG YingBo | 2007 | Chinese Science Bulletin2007，52，A01： | 17 |
| 6 | Formation Mechanism and Controlling Factors of Natural Gas Reservoirs of the Jialingjiang Formation in the East Sichuan Basin显示文摘The Lower Triassic Jialingjiang Formation reservoirs are distributed widely in the East Sichuan Basin,which are composed mainly of fractured reservoirs.However,natural gas with high concentration of H_2S,ranging from 4% to 7%,was discovered in the Woionghe Gas pool consisting primarily of porous reservoirs,while the other over 20 fractured gas reservoirs have comparatively low,tiny and even no H_2S within natural gases.Researches have proved the H_2S of the above reservoirs are all from the TSR origin.Most of the Jialingjiang Formation natural gases are mainly generated from Lower Permian carbonate rocks,the Wolonghe gas pool's natural gases are from the Upper Permian Longtan Formation,and the natural gases of the Huangcaoxia and Fuchengzhai gas pools are all from Lower Silurian mudstone.The formation of H_2S is controlled by the characteristics and temperature of reservoirs,and is not necessarily related with gas sources.The Jialingjiang Formation in East Sichuan is buried deeply and its reservoir temperature has ever attained the condition of the TSR reaction.Due to poor reservoir potential,most of the gas pools do not have enough room for hydrocarbon reaction except for the Wolonghe gas pool,and thus natural gases with high H_2S concentration are difficult to be generated abundantly.The south part of East Sichuan did not generate natural gases with high H_2S concentration because the reservoir was buried relatively shallow,and did not suffer high temperature.Hence,while predicting the distribution of H_2S,the characteristics and temperature of reservoirs are the necessary factors to be considerd besides the existence of anhydrite. | ZHU Guangyou ZHANG Shuichang LIANG Yingbo ZHOU Guoyuan WANG Zhengjun | 2007 | Acta Geologica Sinica(English Edition)2007，81，5： | 16 |
| 7 | The genesis of H_2S in the Weiyuan Gas Field, Sichuan Basin and its evidence显示文摘The Sinian Dengying Formation gas pool in Weiyuan is the oldest large-scale sulfur-bearing gas field in China, which has a H2S content ranging from 0.8% to 1.4%. The Cambrian Xixiangchi Formation gas pool discovered recently above the Dengying Formation contains gas geochemical behaviors similar to those of Dengying Formation but different in sulfur isotopes of H2S. Investigations show that though these two Sinian and Cambrian gas pools are separate ones, they share the same Cambrian source rock. The higher dry coefficient, heavier carbon isotopes, sulfur isotopes of sulfide, lower filling of gas pools, formation water characteristics, reservoir properties and H2S distribution, indicate that H2S in both the Sinian and Cambrian gas pools originates from TSR. The sulfur isotopes of sulfates have shown that H2S was formed in respective pools, namely hydrocarbons charged into the pools reacted with the Dengying Formation and the Xixiangchi Formation gypsum (TSR), respectively, to form H2S. Compared with sulfur isotopes of sulfates in each pool, δ34S values of H2S are 8‰ lighter for the Dengying Formation pool and 12‰ lighter for the Xixiangchi Formation pool, respectively, which is attributed to the difference in temperatures of TSR occurrence. The reservoir temperature of the Xixiangchi Formation pool is about 40℃ lower than that of the Dengying Formation pool. Temperature plays a controlling role in both the sulfur isotopic fractionation and amounts of H2S generation during TSR. | ZHU GuangYou ZHANG ShuiChang LIANG YingBo LI QiRong | 2007 | Chinese Science Bulletin2007，52，10： | 13 |
| 8 | Understanding primary and secondary sources of ambient oxygenated volatile organic compounds in Shenzhen utilizing photochemical age-based parameterization method显示文摘Oxygenated volatile organic compounds(OVOCs) are key intermediates in the atmospheric photooxidation process. To further study the primary and secondary sources of OVOCs,their ambient levels were monitored using a proton-transfer reaction mass spectrometer(PTR-MS) at an urban site in the Pearl River Delta of China. Continuous monitoring campaigns were conducted in the spring, summer, fall, and winter of 2016. Among the six types of OVOC species, the mean concentrations of methanol were the highest in each season(up to 13–20 ppbv), followed by those of acetone, acetaldehyde and acetic acid(approximately 2–4 ppbv), while those of formic acid and methyl ethyl ketone(MEK) were the lowest(approximately 1–2 ppbv). As observed from a diurnal variation chart, the OVOCs observed in Shenzhen may have been affected by numerous factors such as their primary and secondary sources and photochemical consumption. The photochemical age-based parameterization method was used to apportion the sources of ambient OVOCs. Methanol had significant anthropogenic primary sources but negligible anthropogenic secondary sources during all of the seasons. Acetone, MEK and acetic acid were mostly attributed to anthropogenic primary sources during each season with smaller contributions from anthropogenic secondary sources. Acetaldehyde had similar contributions from both anthropogenic secondary and anthropogenic primary sources throughout the year.Meanwhile, anthropogenic primary sources contributed the most to formic acid. | Bo Zhu Yu Han Chuan Wang Xiaofeng Huang Shiyong Xia Yingbo Niu Zixuan Yin Lingyan He | 2019 | Journal of Environmental Sciences2019，31，1： | 13 |
| 9 | A discussion on gas sources of the Feixianguan Formation H_2S-rich giant gas fields in the northeastern Sichuan Basin显示文摘In recent years several H2S-rich oolite giant gas pools have been discovered in the Lower Triassic Feixianguan Formation of the northeastern Sichuan basin, and their explored gas reserves have been over 5000×108 m3. However, gas sources remain unsolved due to multiple source horizons with high maturity in this area and TSR alterations. By integrating analytical data of natural gas samples with conprehensive investigations on many factors, such as oil-gas geology, distribution and evolution of source rocks, charging and adjustment of gas pools, mixture of natural gases and secondery alterations, the present study concluded that the dominant source for the Feixianguan Fr. gas pools is the Permian Longtan Fr. source rock and secondly the Silurian Longmaxi Fr. source rock. Natural gases from the various gas pools differ genetically due to the matching diversity of seal configurations with phases of hydrocarbon generation and expulsion by different source rocks, among which natural gases in Puguang Gasfield are dominated by the trapped gas generated from the Longtan Fr. source rock and commingled with the gas cracked from the Silurian crude oil, while those in Dukouhe, Tieshangpo and Luojiazhai Gasfields are composed mainly of the Silurian oil-cracking gas and commingled with the natural gas derived from the Longtan Fr. source rock. | ZHANG ShuiChang ZHU GuangYou CHEN JianPing LIANG YingBo | 2007 | Chinese Science Bulletin2007，52，A01： | 12 |
| 10 | Origin and Distribution of Hydrogen Sulfide in Oil-Bearing Basins,China显示文摘The concentration of hydrogen sulfide gas (H2S) varies greatly in the oil-bearing basins of China, from zero to 90%. At present, oil and gas reservoirs with high H2S concentration have been discovered in three basins, viz. the Bohai Bay Basin, Sichuan Basin and the Tarim Basin, whereas natural gas with low H2S concentration has been found in the Ordos Basin, the Songliao Basin and the Junggar Basin. Studies suggest that in China H2S origin types are very complex. In the carbonate reservoir of the Sichuan Basin, the Ordos Basin and the Tarim Basin, as well as the carbonate-dominated reservoir in the Luojia area of the Jiyang depression in the Bohai Bay Basin, Wumaying areas of the Huanghua depression, and Zhaolanzhuang areas of the Jizhong depression, the H2S is of Thermochemical Sulfate Reduction (TSR) origin. The H2S is of Bacterial Sulphate Reduction (BSR) origin deduced from the waterflooding operation in the Changheng Oilfield (placanticline oil fields) in the Songliao Basin. H2S originates from thermal decomposition of sulfur-bearing crude oil in the heavy oil area in the Junggar Basin and in the Liaohe heavy oil steam pilot area in the western depression of the Bohai Bay Basin. The origin types are most complex, including TSR and thermal decomposition of sulfcompounds among other combinations of causes. Various methods have been tried to identify the origin mechanism and to predict the distribution of H2S. The origin identification methods for H2S mainly comprise sulfur and carbon isotopes, reservoir petrology, particular biomarkers, and petroleum geology integrated technologies; using a combination of these applications can allow the accurate identification of the origins of H2S. The prediction technologies for primary and secondary origin of H2S have been set up separately. | ZHU Guangyou ZHANG Shuichang LIANG Yingbo | 2009 | Acta Geologica Sinica(English Edition)2009，83，6： | 8 |
| 11 | Formation mechanism and geochemical characteristics of shallow natural gas in heavy oil province,China显示文摘Shallow gas reservoirs are distributed widely in Chinese heavy oil-bearing basins.At present,shallow gas resources have opened up giant potentials.The previous researches indicate the intimate genetic relationship between shallow gas and heavy oil.Shallow gas resources are generated from crude oil degraded by anaerobic microscopic organism,it belongs to biogenic gas family of secondary genesis, namely heavy oil degraded gas.Shallow gas resources are usually distributed in the upward position or the vicinity of heavy oil reservoirs.They are mainly of dry gas,which are composed of methane and only tiny C2 + heavy hydrocarbon and relatively higher contents of nitrogen gas.Generally,methane isotopes are light,whose values are between biogenic gas and thermal cracking gas.Ethane isotopes are heavy,which mixed possibly with thermogenic gas.Carbon dioxide bear the characteristics of very heavy carbon isotope,so carbon isotopic fractionation effects are very obvious on the process of microscopic organism degradation crude oil.The heavy oil degraded gas formation,a very complex geological,geochemical and microbiological geochemical process,is the result of a series of reactions of organic matter-microbes and water-hydrocarbon,which is controlled by many factors. | ZHU GuangYou,ZHANG ShuiChang,ZHAO WenZhi,WANG ZhengJun,LIANG YingBo, ZHAO XueFeng&ZHANG JingYan PetroChina Oil Geologic Lab Center,Research Institutes of PetroChina Exploration and Development,Beijing 100083,China | 2008 | Science China Earth Sciences2008，51，S1： | 4 |

| 14 | Key immunity characteristics of diverse stages of brucellosis in rural population from Inner Mongolia, China显示文摘Background: Brucellosis poses a serious threat to human and animal health,particularly in developing countries such as China.The Inner Mongolia Autonomous Region is one of the most severely brucellosis-endemic provinces in China.Currently,the host immune responses functioning to control Brucella infection and development remain poorly understood.The aim of this study is to further clarify the key immunity characteristics of diverse stages of brucellosis in Inner Mongolia.Methods: We collected a total of 733 blood samples from acute(n=137),chronic(n=316),inapparent(n=35),recovery(n=99),and healthy(n=146)groups from the rural community of Inner Mongolia between 2014 and 2015.The proportions of CD4^(+),CD8^(+),Th1,Th2,and Th17 T cells in peripheral blood and the expression of TLR2 and TLR4 in lymphocytes,monocytes and granulocytes were examined using flow cytometry analysis.The differences among the five groups were compared using one-way ANOVA and the Kruskal–Wallis method,respectively.Results: Our results revealed that the proportions of CD4^(+) and CD8^(+) T cells were significantly different among the acute,chronic,recovery,and healthy control groups(P<0.05),with lower proportions of CD4^(+) T cells and a higher proportion of CD8^(+) T cells in the acute,chronic,and recovery groups.The proportion of Th1 cells in the acute,chronic,and inapparent groups was higher than that in the healthy and recovery groups;however,there was no significant difference between patients and healthy individuals(P>0.05).The proportion of Th2 lymphocytes was significantly higher in the acute and healthy groups than in the inapparent group(P<0.05).The proportion of Th17 cells in the acute group was significantly higher than that in the healthy control,chronic,and inapparent groups(P<0.05).Finally,the highest expression of TLR4 in lymphocytes,monocytes and granulocytes was observed in the recovery group,and this was followed by the acute,chronic,healthy control,and inapparent groups.There was a significant difference between the recovery group and the other groups,except for the acute group(P<0.05).Moreover,a correlation in TLR4 expression was observed in lymphocytes,monocytes and granulocytes among the five groups(r>0.5),except for the inapparent group between lymphocytes and granulocytes(r=0.34).Conclusions: Two key factors(CD8^(+)T cells and TLR4)in human immune profiles may closely correlate with the progression of brucellosis.The detailed function of TLR4 in the context of a greater number of cell types or tissues in human or animal brucellosis and in larger samples should be further explored in the future. | Yongzhang Zhu Li Shi Yige Zeng Dongri Piao Yingbo Xie Juan Du Meng Gao Wei Gao Junli Tian Jun Yue Min Li XiaoKui Guo Yufeng Yao YaoXia Kang | 2022 | Infectious Diseases of Poverty2022，11，3： | 1 |
