| 2 | Development of the theory and technology for low permeability reservoirs in China显示文摘The development theories of low-permeability oil and gas reservoirs are refined, the key development technologies are summarized, and the prospect and technical direction of sustainable development are discussed based on the understanding and research on developed low-permeability oil and gas resources in China. The main achievements include:(1) the theories of low-permeability reservoir seepage, dual-medium seepage, relative homogeneity, etc.(2) the well location optimization technology combining favorable area of reservoir with gas-bearing prediction and combining pre-stack with post-stack;(3) oriented perforating multi-fracture, multistage sand adding, multistage temporary plugging, vertical well multilayer, horizontal and other fracturing techniques to improve productivity of single well;(4) the technology of increasing injection and keeping pressure, such as overall decreasing pressure, local pressurization, shaped charge stamping and plugging removal, fine separate injection, mild advanced water injection and so on;(5) enhanced recovery technology of optimization of injection-production well network in horizontal wells. To continue to develop low-permeability reserves economically and effectively, there are three aspects of work to be done well:(1) depending on technical improvement, continue to innovate new technologies and methods, establish a new mode of low quality reservoir development economically, determine the main technical boundaries and form replacement technology reserves of advanced development;(2) adhering to the management system of low cost technology & low cost, set up a complete set of low-cost dual integration innovation system through continuous innovation in technology and management;(3) striving for national preferential policies. | HU Wenrui WEI Yi BAO Jingwei | 2018 | Petroleum Exploration and Development2018，45，4： | 1 |
| 3 | Orthorhombic Y_(0.95-x)Sr_(x)Co_(0.3)Fe_(0.7)O_(3-δ) anode for oxygen evolution reaction in solid oxide electrolysis cells显示文摘Cubic perovskite oxides usually suffer from delamination and Sr^(2+) segregation for catalyzing oxygen evolution reaction (OER) at the anodes of solid oxide electrolysis cells (SOECs). It is crucial to develop alternative and efficient anode materials for SOECs. Herein, a series of novel Y_(0.95-x)Sr_(x)Co_(0.3)Fe_(0.7)O_(3-δ) (YSCF-x) orthorhombic perovskite oxides in the Pnma (62) space group are synthesized as anode materials of SOECs. Physicochemical characterizations and density functional theory calculations reveal that the partial substitution of Y^(3+) by Sr^(2+) increases the oxygen vacancy concentration and mobility as well as improves the electrical conductivity, which contributes to the excellent OER activity of YSCF-x. At 800 °C, the current density of SOEC with YSCF-0.05-Ce0.8Sm0.2O2-δ anode can reach 1.32 A cm^(−2) at 1.6 V, about twice that of SOEC with Y_(0.95-x)Sr_(x)Co_(0.3)Fe_(0.7)O_(3-δ)-Ce_(0.8)Sm_(0.2)O_(2-δ) anode. This work paves a new avenue for the design of advanced anode materials of SOECs. | Weicheng Feng Yuefeng Song Tianfu Liu Jingwei Li Xiaomin Zhang Junhu Wang Guoxiong Wang Xinhe Bao | 2021 | Fundamental Research2021，1，4： | 0 |
| 4 | Genesis of High Ba-Sr Yashan Intrusion from the Jiaodong Peninsula,Eastern China:Implications for the Destruction of the North China Craton显示文摘The origin of the Mesozoic high Ba-Sr(HBS)granitic magmatism in the Jiaodong Peninsula remains controversial in petrogenesis models and geodynamic settings.Here,we report zircon UPb age,trace element and oxygen isotope compositions,and whole-rock major-trace element and Sr-Nd isotope compositions of the HBS Yashan granodiorite.The zircon U-Pb age of~118 Ma denotes that the Yashan granodiorite belongs to the Weideshan-stage magmatic activity,which is consistent with the age of Mo mineralization in the Yashan intrusion.The low Sr/Y(48.8-115)and high(La/Yb)_(N)(23.8-50.4)ratios of the Yashan granodiorite are analogous to adakitic features derived from the lower-crust.This is also supported by the whole-rock initial^(87)Sr/^(86)Sr ratios(0.7096-0.7103)and zircon δ^(18) O values(6.79‰-8.03‰).Contemporaneous mantle-derived mafic microgranular enclaves indicate the involvement of the metasomatized lithospheric mantle.The high magma oxygen fugacity of the Yashan intrusion as indicated by high zircon Ce^(4+)/Ce^(3+) values suggests the involvement of plate subduction.The obviously lower Dy/Yb,La/Yb and Sr/Y ratios of magmatic rocks in the Weideshan-stage than those in the early-stage imply lithospheric thinning of the eastern North China Craton.We propose that the Yashan HBS granodiorite was formed by crust-mantle interactions during slab rollback. | Guozhi Xie Lipeng Zhang Jie Li Zhongyi Bao Kun Wang Qian Chen Li Wang Jingwei Wang | 2022 | Journal of Earth Science2022，33，3： | 0 |
