| 1 | Origin and Distribution of Groundwater Chemical Fields of the Oilfield in the Songliao Basin,NE China显示文摘There are many factors affecting the chemical characteristics of groundwater in the forming process of groundwater chemical fields, such as freshening due to meteoric water leaching downwards, freshening due to mudstone compaction and water release, concentration due to infiltration and freshening due to dehydration of clay minerals. As a result, the groundwater chemical fields are characterized by lengthwise stages and planar selectivity. The former arouses vertical chemical zonality of groundwater. Five units could be identified downwards in the Songliao basin: (1) freshening zone due to downward-leaching meteoric water, (2) concentration zone due to evaporation near the ground surface, (3) freshening zone due to mudstone compaction and water release, and concentration zone due to compaction and infiltration, (4) freshening zone due to dehydration of clay minerals, and (5) filtration-concentration zone; whereas the latter determines the planar division of groundwater chemical fields: (1) the freshening area due to meteoric water, asymmetrically on the margin of the basin, (2) the freshening area due to mudstone compaction and water release in the central part of the basin, (3) the leaky area, which is a transitional zone, and (4) leakage-evaporation area, which is a concentration zone. In the direction of centrifugal flows caused by mudstone compaction in the depression area, the mineralization degree, concentrations of Na+ and Cl?, and salinity coefficient (SC) increase, while concentrations of (CO32 ?+HCO3 ?) and SO42 ?, metamorphism coefficient (MC) and desulfuration coefficient (DSC) decrease. However, all these parameters increase in the direction of gravity-induced centripetal flows. | JIN Aimin LOU Zhanghua ZHU Rong CAI Xiyuan GAO Ruiqi | 2005 | Acta Geologica Sinica(English Edition)2005，79，5： | 8 |
| 2 | An analytical solution to contaminant advection and dispersion through a GCL/AL liner system显示文摘An one-dimensional model for contaminant advection and dispersion through a GCL/AL liner system was developed to analyze the equivalence between a GCL(geosynthetic clay liner) and a CCL(compacted clay liner).The continuity of contaminant concentration and flux at the interface between the GCL and the underlying attenuation liner(AL) are obeyed in the model,and background concentrations in the soil liner are also considered.Based on the assumption that contaminant transport through a GCL was a steady state process,an analytical solution was obtained.Increasing the leachate head from 0.3 m to 10 m results in a reduction of the breakthrough time of benzene by a factor of 2.7.The breakthrough time of benzene increases by a factor of 7.0 when the hydraulic conductivity of GCL decreases by one order of magnitude.The breakthrough curves are more sensitive to the hydraulic conductivities of the GCL and AL(attenuation layer) than to the thickness of the AL.The standard 75 cm CCL can be replaced by a combination of a GCL and a 1.0-4.0 m thickness of AL.The proposed method can be used for preliminary design of GCL composite liners,assessing the equivalence between GCL and CCL,preliminary design of a remediation method for contaminated soils,and evaluating experimental results. | XIE HaiJian LOU ZhangHua CHEN YunMin JIN AiMin CHEN PeiXiong | 2011 | Chinese Science Bulletin2011，56，8： | 8 |
| 3 | Origin, Flow of Formation Water and Hydrocarbon Accumulation in the Zhenwu Area of the North Jiangsu Basin, China显示文摘In order to understand the origin and flow of formation water and to evaluate the hydrocarbon accumulation and preservation conditions, the properties of formation water chemistry and dynamics of the Zhenwu area in the southern Gaoyou Sag, North Jiangsu Basin, China, have been investigated. The results show that Xuzhuang oilfield is infiltrated discontinuously by meteoric water under gravity, which consequently leads to the desalination of formation water. Formation water in the Zhenwu and Caozhuang oilfields is less influenced by meteoric water infiltration, and the origin is interpreted to be connate water. Hydrocarbon migration, accumulation and preservation are closely related to the hydrodynamic field of formation water. Formation water concentrates gradually during the process of centrifugal flow released by mudstone compaction and the centripetal flow of meteoric water infiltration, leading to the high salinity of the central part. The geological conditions of the southern fault-terrace belt are poor for hydrocarbon accumulation and preservation as meteoric water infiltration, leaching and oxidation, while the central part, i.e., northern Zhenwu and Caozhuang oilfields is beneficial for an abundance of hydrocarbon accumulation. Most of the large scale oil-gas fields locate herein. | LI Mei LOU Zhanghua JIN Aimin ZHU Rong SHANG Changjian YE Ying ZHU Zhenhong | 2013 | Acta Geologica Sinica(English Edition)2013，87，3： | 8 |
| 4 | Distribution and Geochemical Characteristics of Fluids in Ordovician Marine Carbonate Reservoirs of the Tahe Oilfield显示文摘The Ordovician carbonate reservoirs in the Tahe Oilfield are highly heterogeneous, which have undergone multiple superimposed transformations by tectonic activities and karst processes, leading to an extremely complex fluid distribution. The geochemical characteristics of geofluids also display great disparities. Results show that the vertical distribution of oil and gas are continuous, however the oil-water interfaces in different blocks of the Tahe Ordovician Oilfield are numerous. Meteoric water infiltration is regarded as the main reason for the high oil-water interface and high water content to the north of Tahe Oilfield, especially in well blocks S78–S73. The isotopic values of deuterium-oxygen in the groundwater and carbon-oxygen from calcite veins confirm that formation water in Ordovician reservoirs of the Tahe Oilfield was a mix of meteoric water and connate water, and the proportion of meteoric water gradually increases from south to north, while connate water decreases. The Tahe Ordovician reservoirs are characterised by multiple hydrocarbon charges, and the general migrating direction is from southeast to northwest and from east to west. High production could be obtained in the northern area of the Tahe Oilfield since the oil layers are thick and oil is highly saturated. The residual water within the reservoirs is low, and heavy oil is dominant in this area. Only a small amount of pore water has been replaced by oil in the southern Tahe Oilfield, leading to low oil saturation and a high content of residual water. Crude oil is herein mainly of medium-light type. During the process of exploration in this region, acid fracturing reformation is usually required for wells to increase their output; however the yield is still low. | Mei Li Zhanghua Lou Rong Zhu Aimin Jin Ying Ye | 2014 | Journal of Earth Science2014，25，3： | 7 |

| 9 | Upper Paleozoic Marine Shale Characteristics and Exploration Prospects in the Northwestern Guizhong Depression,South China显示文摘Multiple sets of organic-rich shales developed in the Upper Paleozoic of the northwestern Guizhong Depression in South China. However, the exploration of these shales is presently at a relatively immature stage. The Upper Paleozoic shales in the northwestern Guizhong Depression, including the Middle Devonian Luofu shale, the Nabiao shale, and the Lower Carboniferous Yanguan shale, were investigated in this study. Mineral composition analysis, organic matter analysis(including total organic carbon(TOC) content, maceral of kerogen and the vitrinite reflection(Ro)), pore characteristic analysis(including porosity and permeability, pore type identification by SEM, and pore size distribution by nitrogen sorption), methane isothermal sorption test were conducted, and the distribution and thickness of the shales were determined, Then the characteristics of the two target shales were illustrated and compared. The results show that the Upper Paleozoic shales have favorable organic matter conditions(mainly moderate to high TOC content, type Ⅰ and Ⅱ_1 kerogen and high to over maturity), good fracability potential(brittleness index(BI) > 40%), multiple pore types, stable distribution and effective thickness, and good methane sorption capacity. Therefore, the Upper Paleozoic shales in the northern Guizhong Depression have good shale gas potential and exploration prospects. Moreover, the average TOC content, average BI, thickness of the organic-rich shale(TOC > 2.0 wt%) and the shale gas resources of the Middle Devonian shales are better than those of the Lower Carboniferous shale. The Middle Devonian shales have better shale gas potential and exploration prospects than the Lower Carboniferous shales. | ZHU Zhenhong YAO Genshun LOU Zhanghua JIN Aimin ZHU Rong JIN Chong CHEN Chao | 2018 | Journal of Ocean University of China2018，17，4： | 2 |

| 19 | S-O bond chemically constrained NiS2/rGO nanocomposite with enhanced Na-ion storage capacity显示文摘NiS2 has become a research hotspot of anode materials for Na-ion batteries due to its high theoretical specific capacity.However,the volume effect,the dissolution of polysulfide intermediates and the low conductivity during the charge/discharge process lead to the low specific capacity and poor cycling stability.NiS2/rGO nanocomposite was prepared by a facile two-step process:GO was prepared by modified Hummers method,and then NiS2/rGO nanocomposite was synthesized by L-cys assisted hydrothermal method.NiS2/rGO nanocomposite shows excellent cycle performance and rate performance,which could be attributed to the mesoporous structure on the graphene skeleton with high conductivity.Besides,the chemical constraint of a unique S—O bond on NiS2 could inhibit the dissolution of intermediates and the loss of irreversible capacity. | Shuyu Zhou Xiaozhe Jin Shengming Zhu Qian Luo Zhiwen Qiu Aimin Wu Hao Huang | 2020 | Chinese Chemical Letters2020，31，9： | 1 |
