| 2 | Status and Trends in Research on Deep-Water Gravity Flow Deposits显示文摘Deep-water gravity flows are one of the most important sediment transport mechanisms on Earth. After 60 years of study,significant achievements have been made in terms of classification schemes,genetic mechanisms,and depositional models of deep-water gravity flows. The research history of deep-water gravity flows can be divided into five stages: incipience of turbidity current theory; formation of turbidity current theory; development of deep-water gravity flow theory; improvement and perfection of deep-water gravity flow theory; and comprehensive development of deep-water gravity flow theory. Currently,three primary classification schemes based on the sediment support mechanism,the rheology and transportation process,and the integration of sediment support mechanisms,rheology,sedimentary characteristics,and flow state are commonly used.Different types of deep-water gravity flow events form different types of gravity flow deposits. Sediment slump retransportation mainly forms muddy debris flows,sandy debris flows,and surge-like turbidity currents. Resuspension of deposits by storms leads to quasi-steady hyperpycnal turbidity currents(hyperpycnal flows). Sustainable sediment supplies mainly generate muddy debris flows,sandy debris flows,and hyperpycnal flows. Deep-water fans,which are commonly controlled by debris flows and hyperpycnal flows,are triggered by sustainable sediment supply; in contrast,deep-water slope sedimentary deposits consist mainly of debris flows that are triggered by the retransportation of sediment slumps and deep-water fine-grained sedimentary deposits are derived primarily from finegrained hyperpycnal flows that are triggered by the resuspension of storm deposits. Harmonization of classification schemes,transformation between different types of gravity flow deposit,and monitoring and reproduction of the sedimentary processes of deep-water gravity flows as well as a source-to-sink approach to document the evolution and deposition of deep-water gravity flows are the most important research aspects for future studies of deep-water gravity flows study in the future. | YANG Tian CAO Yingchang WANG Yanzhong LI Ya ZHANG Shao Min | 2015 | Acta Geologica Sinica(English Edition)2015，89，2： | 18 |
| 3 | Characteristics and origin of abnormally high porosity zones in buried Paleogene clastic reservoirs in the Shengtuo area, Dongying Sag, East China显示文摘There are three abnormally high porosity zones developed in buried Paleogene nearshore subaqueous fan and sublacustrine fan clastic reservoirs at 2,800-3,200 m, 3,250-3,700 m and 3,900-4,400 m, respectively, within the Shengtuo area of the Dongying Sag. Here the porosity of reservoirs buried deeper than 4,000 m can still be greater than 20%. Investigation of these three abnormally high porosity(AHP) zones in the 3rd to 4th member of the Paleogene Shahejie Formation in the Shengtuo area was carried out with utilization of core observation, thin section identification, SEM observation, image analysis, core physical property testing and other technical methods. The results show that, the AHP zones in 2,800-3,200 m and 3,250-3,700 m are visible pores primary AHP zones dominated by significant primary intergranular pores(more than 50% of the total porosity), while secondary pores and micropores in authigenic clays may develop in some reservoirs. AHP reservoirs in the AHP zone of 3,900-4,400 m are dominated by micropores in matrix, visible pores are mainly grain dissolution pores but with low absolute content(< 1%), so this zone belongs to the micropores primary AHP zone. The genesis of the three AHP zones was studied to distinguish between porosity enhancement and porosity preservation. Our research shows that, in deeply buried clastic reservoirs in the Shengtuo area, mineral dissolution occurred in a relatively closed diagenetic system with high temperature and high salinity. Reservoir rocks underwent extensive feldspar dissolution, while detrital carbonate grains and carbonate cements show no evidence of extensive dissolution. Although significant feldspar dissolution pores developed, feldspar dissolution enhanced porosity only a little due to the precipitation of almost isovolumetric dissolution products in the nearby primary intergranular pores in forms of authigenic clays and quartz cements. Net enhanced porosity originating from feldspar dissolution is generally less than 0.25%. Thus, the subsurface dissolution has little impact on the mid-deep buried high porosity reservoirs. Reservoirs in braided channels of middle fans in sublacustrine fans and reservoirs in the middle-front of fan bodies of nearshore subaqueous fans provide the basis for the development of AHP zones. The shallow development of fluid overpressure and early hydrocarbon emplacement have effectively retarded compaction and carbonate cementation, so that the high porosity in the superficial layers is preserved in the mid-deep layers. These are the main controlling factors in the development of AHP zones. | Cao Yingchang Yuan Guanghui Li Xiaoyan Wang Yanzhong Xi Kelai Wang Xiaoming Jia Zhenzhen Yang Tian | 2014 | Petroleum Science2014，11，3： | 18 |
| 4 | Analysis of petrophysical cutoffs of reservoir intervals with production capacity and with accumulation capacity in clastic reservoirs显示文摘Methodologies have been developed for calculating cutoffs of reservoir intervals with production capacity(RIPC) and reservoir intervals with accumulation capacity(RIAC) according to the types of pore throat structures and dynamic force by using data from petrophysical analysis, production tests and mercury injection. The data are from clastic reservoirs in the third member(Es3) and the fourth member(Es4) of the Shahejie Formation in the Shengtuo area on the North Slope of the Dongying Sag, Jiyang Depression, China. The method of calculating cutoffs of RIPC is summarized as follows: 1) determination of permeability cutoffs of RIPC; 2) classification of types of pore-throat structures according to mercury injection data and then relating porosity to permeability and determining the relationship between porosity and permeability according to each type of pore-throat structure; and 3) calculating porosity cutoffs of RIPC using established correlation between porosity and permeability according to the type of pore throat structure. The method of calculating cutoffs of RIAC includes: 1) establishing a functional relationship between oil-water interfacial tension and formation temperature; 2) calculating limiting values of maximum connected pore-throat radii according to formation temperature and dynamic forces of each reservoir interval; 3) correlating permeability with maximum connected pore-throat radius and then obtaining permeability cutoffs of RIAC; and 4) calculating porosity cutoffs on the basis of permeability cutoffs according to specific correlations, suitable for the type of porethroat structure. The results of this study show that porosity and permeability cutoffs of clastic reservoirs decrease with depth. For a fixed permeability cutoff, the porosity cutoff of RIPC varies because the type of pore throat is different. At a fixed temperature, porosity and permeability cutoffs of RIAC decrease as dynamic force increases. For a fixed permeability cutoff of effective hydrocarbon accumulation, the porosity cutoff also varies with different types of pore throat. | Wang Yanzhong Cao Yingchang Song Guoqi Song Ling Yang Tian Zhang Shaomin | 2014 | Petroleum Science2014，11，2： | 4 |
| 5 | Applications of Light Stable Isotopes(C, O, H) in the Study of Sandstone Diagenesis: A Review显示文摘This article reviews the applications of light stable isotope, including carbon, oxygen and hydrogen, in thestudies on origin and formation temperature of authigenic carbonate, quartz and clay minerals. Theoretical knowledge andanalytical methods for major light stable isotopes are introduced in detail. Negative and positive δ^(13)C values indicatesignificant differences on the origin of carbonate cements. The δ^(18)O value is an effective palaeotemperature scale forauthigenic minerals formation. Various fractionation equations between δ^(18)O and temperature are proposed for carbonatecements, quartz cements and clay minerals, whose merit and demerit, applicable conditions are clarified clearly. Clumpedisotope analysis can reconstruct the temperature of carbonate precipitation with no requirement on the δ^(18)O of initial waters,which makes temperature calculation of carbonate cements formation more convenient and accurate. Hydrogen and oxygenisotopes mainly reflect the origin of diagenetic fluid for clay mineral formation, providing reliable evidence for diageneticenvironment analysis. This work aims at helping researchers for better understanding the applications of light stable isotopein sandstone diagenesis. | XI Kelai CAO Yingchang LIN Miruo LIU Keyu WU Songtao YUAN Guanghui YANG Tian | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 4 |
| 6 | RIS-Aided Constant-Envelope Beamforming for Multiuser Wireless Power Transfer:A Max-Min Approach显示文摘As a revolutionary hardware technology that can reconfigure the propagation environment,reconfigurable intelligent surfaces(RISs)have been regarded as a promising solution to enhance wireless networks.In this paper,we consider a multiuser multiple-input single-output(MISO)wireless power transfer(WPT)system,which is assisted by several RISs.In order to improve energy efficiency and reduce hardware cost,we consider that the energy transmitter(ET)in the WPT system is equipped with a constant-envelope analog beamformer,instead of a digital beamformer.Focusing on user fairness,we study a minimum received power maximization problem by jointly optimizing the ET beamforming and the RIS phase shifts,subject to the constant-envelope constraints.We iteratively solve this non-convex maxmin problem by leveraging both the successive convex approximation(SCA)method and the alternating direction method of multipliers(ADMM)algorithm.Numerical results demonstrate the effectiveness of the proposed algorithm and show attractive performance gain brought by RISs. | Huiyuan Yang Chang Cai Xiaojun Yuan Yingchang Liang | 2021 | China Communications2021，18，3： | 3 |
| 7 | Deep-water gravity flow deposits in a lacustrine rift basin and their oil and gas geological significance in eastern China显示文摘The types,evolution processes,formation mechanisms,and depositional models of deep-water gravity flow deposits in a lacustrine rift basin are studied through core observation and systematic analysis.Massive transport of slide and slump,fluid transport of debris flow and turbidity currents are driven by gravity in deep-water lacustrine environment.The transformation between debris flow and turbidity current,and the transformation of turbidity current between supercritical and subcritical conditions are the main dynamic mechanisms of gravity flow deposits in a lake basin.The erosion of supercritical turbidity current controls the formation of gravity-flow channel.Debris flow deposition gives rise to tongue shape lobe rather than channel.Deep-water gravity flow deposits are of two origins,intrabasinal and extrabasinal.Intrabasinal gravity flow deposits occur as single tongue-shape lobe or fan of stacking multiple lobes.Extrabasinal gravity-flow deposits occur as sublacustrine fan with channel or single channel sand body.However,the nearshore subaqueous fan is characterized by fan of stacking multiple tongue shape lobes without channel.The differential diagenesis caused by differentiation in the nearshore subaqueous fan facies belt results in the formation of diagenetic trap.The extrabasinal gravity flow deposits are one of the important reasons for the abundant deep-water sand bodies in a lake basin.Slide mass-transport deposits form a very important type of lithologic trap near the delta front often ignored.The fine-grained sediment caused by flow transformation is the potential'sweet spot'of shale oil and gas. | CAO Yingchang JIN Jiehua LIU Haining YANG Tian LIU Keyu WANG Yanzhong WANG Jian LIANG Chao | 2021 | Petroleum Exploration and Development2021，48，2： | 2 |

| 11 | Treatment of STAT5b-RARA positive acute promyelocytic leukemia by Venetoclax combining with homoharringtonine, cytarabine: A case report and literature review显示文摘Introduction:Acute promyelocytic leukemia(APL)is mostly due to the chromosome translocation t(15;17)(q22;q12),leading to the formation of PML-RARA fusion protein.Some patients carried rare translocation involving RARA gene,who were called variant APL caused by RAR family(RARA,RARB,and RARG)and partner genes.STAT5b-RARA was a rare type of molecular genetic abnormality with unfavorable prognosis which have been reported in only 18 cases in variant APL.Knowledge of STAT5b-RARA(+)APL treatment is still limited.Case report:We presented a 38-year-old female variant APL case,who was STAT5b-RARA positive detected by reverse transcription polymerase chain reaction.The patient failed to respond after four-drug combined induction chemotherapy:idarubicin,cytarabine,all trans retinoic acid,and arsenic trioxide(As 2 O 3).Then,the patient was re-induced with azacytidine,but still failed to achieve complete remission(CR).Next,she was treated with Venetoclax combining with homoharringtonine and cytarabine as the salvage therapy and achieved CR.Later,the patient received hematopoietic stem cell transplantation after 4 cycles of consolidation therapy.Conclusion:Venetoclax combining with homoharringtonine and cytarabine has been used as the salvage therapy in the STAT5b-RARA positive APL successfully. | Guangji Zhang Yang Song Li Wan Kaiqi Liu Shaowei Qiu Jianxiang Wang Yingchang Mi | 2022 | Blood Science2022，4，2： | 1 |

| 13 | Reservoir Quality and Diagenesis of the Permian Lucaogou Formation Tight Carbonates in Jimsar Sag, Junggar Basin, West China显示文摘The Lower Permian Lucaogou Formation in the Jimsar sag, Junggar Basin is a typical tight-oil reservoir in China. For effective exploration and production, the formation of a high-quality reservoir must be thoroughly studied. In this work, the tight-oil reservoir was examined using a variety of methods, including core and thin-section observations, XRD, SEM, CL and fluid inclusion and isotope testing. The tight-oil reservoirs were primarily deposited in saline lake environments, which are dominated by variable admixture of dolomite, quartz, feldspar, tuff, calcite and pyrite. Nine main lithofacies were identified:(1) siliceous mudstone,(2) dolomitic siliceous mudstone,(3) dolomitic mudstone,(4) intraclast packstone/grainstone,(5) ooid grainstone,(6) bioclast grainstone,(7) dolomitic siltstone,(8) mixed siliclastic and intraclast grainstone and(9) brecciated dolomitic mudstone. The pore types are classified into four categories: primary intergranular, moldic, intercrystalline and fracture pores. The properties of tight-oil reservoirs are quite poor, with low porosity(ave. 7.85%) and permeability(ave. 0.110 mD) and a small pore-throat radius(ave. 0.086 μm). The tight-oil reservoirs are dominated by the aggradation of a repetitive meter-scale sedimentary facies succession that records distinct lacustrine expansions and contractions. These tight carbonates have also undergone significant diagenetic alterations, such as dolomitization, dissolution, neomorphism and fracture created intercrystalline and moldic pores, vug and fractures; chemical and mechanical compaction and carbonate cementation have decreased the reservoir quality. Variations in reservoir quality in the Jimusar sag are due to a combination of lithofacies type, high-frequency cyclic depositional architecture, dissolution intensity, dolomitization and tectonic related deformation. This integrated study has helped in understanding the reservoir heterogeneity and hydrocarbon potential of the Jimusar fine-grained rocks. | Yongqiang Yang Longwei Qiu Yingchang Cao Cheng Chen Dewen Lei Ming Wan | 2017 | Journal of Earth Science2017，28，6： | 1 |

| 16 | Micron-scale 1:5H-based precipitated phase with the lamellar structure of sintered Sm_(2)Co_(17)-based magnets and its potential application显示文摘The excellent thermal stability of magnetic properties of Sm_(2)Co_(17)-based magnets is their most impor-tant feature.However,this stability is reduced when the maximum energy product of Sm_(2)Co_(17)-based magnets is improved,which is mainly determined by the Fe/Cu distribution of the 2:17R cell and 1:5H cell boundary phases.During the demagnetization process,the Cu-rich 1:5H cell boundary phase with a width of 2-15 nm obstructs the motion of the domain walls,yielding coercivity.Herein,we report a micron-scale Cu/Zr-rich and Fe-lean 1:5H-based precipitated phase with a lamellar structure,probably induced by Sm_(2)O_(3) doping.This structure enables the separate regulation of Fe and Cu distribution for Sm_(2)Co_(17)-based magnets with Fe-rich 2:17R cell phases and Cu-rich 1:5H cell boundary phases,consid-erably optimizing the thermal stability of magnetic properties.This discovery can be further developed to produce Sm_(2)Co_(17)-based magnets with high performance and excellent thermal stability of magnetic properties. | Nengjun Yu Yingchang Li Zesong Ren Minxiang Pan Hangfu Yang Qiong Wu Hongliang Ge Minggang Zhu Wei Li | 2023 | Journal of Materials Science & Technology2023，，22： | 0 |
| 17 | Effects of genetic polymorphisms on methotrexate levels and toxicity in Chinese patients with acute lymphoblastic leukemia显示文摘Methotrexate(MTX)has an antitumor effect when used for the treatment of acute lymphoblastic leukemia(ALL).This study aims at evaluating the associations between 14 polymorphisms of six genes involved in MTX metabolism with serum MTX concentration and toxicity accompanying high-dose MTX.Polymorphisms in 183 Chinese patients with ALL were analyzed using TaqMan single nucleotide polymorphism genotyping assay.The serum MTX concentration was determined using homogeneous enzyme immunoassay.MTX-related toxicities were also evaluated.Renal toxicity was significantly associated with higher serum MTX concentrations at 24,48,and 72 hours,and MTX elimination delay(P=0.001,P<0.001,P<0.001,and P<0.001,respectively),whereas SLCO1B1 rs4149056 was associated with serum MTX concentrations at 48 and 72 hours,and MTX elimination delay in candidate polymorphisms(P=0.014,P=0.019,and P=0.007,respectively).SLC19A1 rs2838958 and rs3788200 were associated with serum MTX concentrations at 24 hours(P=0.016,P=0.043,respectively).MTRR rs1801394 was associated with serum MTX concentrations at 72 hours(P=0.045).Neutropenia was related to SLC19A1 rs4149056(odds ratio[OR]:3.172,95%confidence interval[CI]:1.310–7.681,P=0.011).Hepatotoxicity was associated with ABCC2 rs2273697(OR:3.494,95%CI:1.236–9.873,P=0.018)and MTRR rs1801394(OR:0.231,95%CI:0.084–0.632,P=0.004).Polymorphisms of SLCO1B1,SLC19A1,ABCC2,and MTRR genes help predict higher risk of increased MTX levels or MTX-related toxicities in adult ALL patients. | Qishan Hao Yang Song Qiuyun Fang Yani Lin Long Chen Xiaodan Wang Ping Zhang Zhe Wang Xiaoyuan Gong Kaiqi Liu Qinghua Li Zheng Tian Min Wang Jianxiang Wang Yingchang Mi | 2023 | Blood Science2023，5，1： | 0 |
