| 1 | Ultra-broadband,fast,and polarization-sensitive photoresponse of low-symmetry 2D NdSb_(2)显示文摘Broadband photodetectors with polarization-sensitive ability have received extraordinary attention for modern optoelectronic devices.Ideal photodetectors should possess high responsivity,fast response,and good stability,which are rare to meet at the same time in one low-symmetric two-dimentional(2D)material.In this work,neodymium diantimonides(RSb_(2)),a member of light rare-earth diantimonides RSb_(2)(R=La–Nd,Sm)with low-symmetry structure,is introduced as a fascinating highly anisotropic 2D material for broadband detection(532 nm to 4μm).The photodetector exhibits a responsivity of 0.49 mA·W^(−1)with 15μs response time at 532 nm and highly stable performance under ambient conditions over 8 months.Furthermore,we identify the polarization-sensitive photoresponse of the detector and demonstrate a high anisotropic factor~1.6.In addition,strong inplane anisotropy is revealed by anisotropic phonon response and the photodetection mechanism is investigated by scanning photocurrent microscopy measurements.This pioneer work on RSb_(2)paves the way for further exploration of 2D RSb_(2)for high performance polarized photodetectors with fast photothermoelectric response. | Gang Li Hanlin Zhang Yong Li Shiqi Yin Xucai Kan Wensen Wei Haifeng Du Binghui Ge Chao An Mingliang Tian Feng Yan Sanjun Yang Tianyou Zhai Liang Li | 2022 | Nano Research2022，15，6： | 1 |

| 3 | Identification of sweet spots in shale-type and siltstone-type“shale oil systems”:A case study of the Chang 7 Member in Ordos Basin显示文摘Mid-high maturity shale oil is the most realistic field for the scale breakthrough of terrestrial shale oil production in China.Generally,three deficiencies hinder shale oil development in China:heavy oil density,small sweet spot areas,and poor distribution continuity.Thus,identifying the“sweet spots”in shale oil reservoirs is critical for the efficient exploration and development of terrestrial shale oil.This study targets the siltstone type(Class-Ⅱshale oil)and pure shale type(Class-Ⅲshale oil)of the Chang 7 Member in the Ordos Basin,and identifies three stratigraphic units,namely the hydrocarbon accumulation unit,hydrocarbon generation unit,and hydrocarbon retention unit,which together constitute the in-source“shale oil system”.The hydrocarbon accumulation unit is mainly siltstone,where the hydrocarbons are migrated from shales.It has favorable porethroat network connectivity with a pore connectivity ratio of 32–57%,being the siltstone-type sweet spots.The hydrocarbon generation unit is mainly composed of high-TOC mudstone/shale and is the main contributor to in-source hydrocarbon generation and expulsion.This unit has high three-dimensional connectivity(28–30%),as shown by the pore-throat network model,associated with vertical paths for hydrocarbon expulsion.The hydrocarbon retention unit is mainly composed of low-TOC mudstone/shale retaining self-generated and migrated hydrocarbons.The pore connectivity rate is 17–42%,and the pore-throat network connectivity direction is uneven.Light and low-carbon-number hydrocarbons are preferentially trapped or even sealed in small pores of the retention unit,forming the typical mudstone/shale-type sweet spots.In the process called shale oil intrasource migration,the oil migrates in source rocks causing component fractionation,which allows more shale oil to enrich in the hydrocarbon accumulation and retention units to form sweet spots,compared with the hydrocarbon generation unit.The migration paths include the one from mudstone/shale to siltstone interlayers and that from the high-TOC mudstone/shale intervals to the low-TOC intervals.The in-source accumulation of shale oil shows the differentiated enrichment model featuring“high-TOC mudstone/shale generating hydrocarbons,low-TOC mudstone/shale retaining hydrocarbons,siltstone accumulating hydrocarbons and multiple intra-source migration paths”.In the Ordos Basin,the organic-lean(TOC 1–3%)mudstone/shale intervals appear to be the sweet spots of shale oil,where there are abundant medium-short-chain hydrocarbons retained with high flowability.After fracturing stimulation,their production conditions may be even superior to those of siltstones.This proposed idea changes the previous strategy to look for sweet spots in high-TOC intervals derived from the shale gas industry. | Songqi PAN Qiulei GUO Caineng ZOU Zhenhua JING Ming YUAN Ying HE He ZHENG Ying MU Zhi YANG Shixiang LI Xinping ZHOU Songtao WU Hanlin LIU Feng YANG Yuanjia HAN | 2023 | Science China Earth Sciences2023，66，7： | 1 |
| 4 | Unconventional Petroleum Sedimentology:A Key to Understanding Unconventional Hydrocarbon Accumulation显示文摘The commercial exploitation of unconventional petroleum resources(e.g.,shale oil/gas and tight oil/gas)has drastically changed the global energy structure within the past two decades.Sweet-spot intervals(areas),the most prolific unconventional hydrocarbon resources,generally consist of extraordinarily high organic matter(EHOM)deposits or closely associated sandstones/carbonate rocks.The formation of sweet-spot intervals(areas)is fundamentally controlled by their depositional and subsequent diagenetic settings,which result from the coupled sedimentation of global or regional geological events,such as tectonic activity,sea level(lake level)fluctuations,climate change,bottom water anoxia,volcanic activity,biotic mass extinction or radiation,and gravity flows during a certain geological period.Black shales with EHOM content and their associated high-quality reservoir rocks deposited by the coupling of major geological events provide not only a prerequisite for massive hydrocarbon generation but also abundant hydrocarbon storage space.The Ordovician-Silurian Wufeng-Longmaxi shale of the Sichuan Basin,Devonian Marcellus shale of the Appalachian Basin,Devonian-Carboniferous Bakken Formation of the Williston Basin,and Triassic Yanchang Formation of the Ordos Basin are four typical unconventional hydrocarbon systems selected as case studies herein.In each case,the formation of sweet-spot intervals for unconventional hydrocarbon resources was controlled by the coupled sedimentation of different global or regional geological events,collectively resulting in a favorable environment for the production,preservation,and accumulation of organic matter,as well as for the generation,migration,accumulation,and exploitation of hydrocarbons.Unconventional petroleum sedimentology,which focuses on coupled sedimentation during dramatic environmental changes driven by major geological events,is key to improve the understanding of the formation and distribution of sweet-spot intervals(areas)in unconventional petroleum systems. | Caineng Zou Zhen Qiu Jiaqiang Zhang Zhiyang Li Hengye Wei Bei Liu Jianhua Zhao Tian Yang Shifa Zhu Huifei Tao Fengyuan Zhang Yuman Wang Qin Zhang Wen Liu Hanlin Liu Ziqing Feng Dan Liu Jinliang Gao Rong Liu Yifan Li | 2022 | Engineering2022，，11： | 1 |
| 5 | World's Energy Transition and Chinese-style Modern Energy Revolution under Carbon Neutrality(Ⅰ)显示文摘Under global consensus on carbon neutrality and the intensification of regional conflicts,new energy has become the primary direction for various countries to achieve energy security and green development.Represented by wind,solar,geothermal,hydrogen and stored energy,and controllable nuclear fusion,the technological and scale advantages of new energy are being continuously strengthened.Low-cost wind,solar,and stored energy will support the global energy transition.The production and utilization of new energy enter a rapid development phase.In 2022,the average global consumption of new energy accounted for 18.2%,and it is expected to reach around 55%by 2050.The distribution of the world's energy resources,consumption regions,technological development,per capita consumption,energy-saving fields,and carbon emissions is uneven.The acceleration of low-carbon development in fossil fuels,the scale-up of renewable energy,and the intelligentization of energy management drives the rapid transition of global energy. | Zou Caineng Xiong Bo Li Shixiang Ma Feng Pan Songqi Liu Hanlin Zhang Guosheng Zhao Qun Guan Chunxiao | 2024 | China Oil & Gas2024，31，1： | 0 |
| 6 | Evolution of lithofacies and paleogeography and hydrocarbon distribution worldwide(I)显示文摘By using a large amount of geological and geophysical data, the geological characteristics such as lithofacies and paleogeography of 4981 geological units at thirteen key geological periods or epoches since the Precambrian in the world have been figured out. The global lithofacies and paleogeography charts have been compiled by ArcGis mapping technology. Combined with the results of plate-paleogeography reconstruction, the lithofacies and paleogeography as well as the prototype basins of these global paleoplates have been restored with the Gplate software. Results show that there are 22 kinds of lithofacies combinations and 10 types of paleogeography units developed since Precambrian. These features of lithofacies and paleogeography as well as their evolution were mainly controlled by the divergent and convergent movements of those plates. Taking the results of the lithofacis and paleogeography at the present and paleoplate location during the seven key geological periods from the Precambrian to Paleozoic for example, during the Late Precambrian and Cambrian, the large-scale disintegration of the Rodinia supercontinent resulted in reduction of uplift denudation area and clastic terrestrial facies area, the expansion of coastal-shallow marine facies and shallow-water carbonate platform. In Devonian, uplift denudation area and clastic terrestrial facies area began to increase and littoral-shallow marine facies area and shallow-water carbonate platform shrank as a result of the formation of Larussia supercontinent. In the Permian, with the formation of the Pangea continent, the development of the global uplift denudation area and clastic terrestrial facies reached its peak, while the littoral and shallow marine facies were very limited in distribution. The lithofacies and paleogeography features and evolution patterns of different stages lay a solid foundation for analyzing the formation conditions of geological elements, such as source rocks, reservoirs and cap rocks for oil and gas accumulation, and revealing the distribution regularity of oil and gas around the world. | ZHANG Guangya TONG Xiaoguang XIN Renchen WEN Zhixin MA Feng HUANG Tongfei WANG Zhaoming YU Bingsong LI Yuejun CHEN Hanlin LIU Xiaobing LIU Zuodong | 2019 | Petroleum Exploration and Development2019，46，4： | 0 |
