CO2-water-shale interaction induced shale microstructural alteration
Junping Zhou,Kang Yang,Shifeng Tian,Lei Zhou,Xuefu Xian,Yongdong Jiang,Muhan Liu,Jianchao Cai,Jianchao Cai,Jianchao Cai +9 more
TL;DR: In this paper, the effect of CO2-water exposure on the micro-structural alteration in shale was investigated and the results indicated that supercritical CO2 (10 MPa, 14 MPa) was more significant than sub-critical CO 2 (6 MPa), which reflected that the roughness and complexity of pore structure and morphology in shale decreased.
Journal ArticleDOI
Experimental investigation on the influence of sub- and super-critical CO2 saturation time on the permeability of fractured shale
Junping Zhou,Shifeng Tian,Lei Zhou,Xuefu Xian,Kang Yang,Yongdong Jiang,Chengpeng Zhang,Yaowen Guo +7 more
TL;DR: In this paper, the effect of subcritical (SubCO2) and supercritical CO2 saturation and its action time on the permeability evolution of fractured shale sample was examined, and five saturation times (4, 10, 12, 18, 24) were introduced to the shale sample.
Journal ArticleDOI
Microstructure and mechanical properties alterations in shale treated via CO2/CO2-water exposure
Junping Zhou,Kang Yang,Lei Zhou,Yongdong Jiang,Xuefu Xian,Chengpeng Zhang,Shifeng Tian,Maolin Fan,Zhaohui Lu +8 more
TL;DR: In this paper, the influence of sub/supercritical CO2-water exposure on the microstructure and mechanical properties of shale was investigated. And the results showed that after sub/ScCO2 and Sub/Sc CO2 water exposure, the contents of carbonate and clay in shale were decreased, while the proportion of micropores and mesopores were decreased.
Journal ArticleDOI
Adsorption Characteristics and Thermodynamic Analysis of CH 4 and CO 2 on Continental and Marine Shale
Kang Yang,Junping Zhou,Xuefu Xian,Chengpeng Zhang,Shifeng Tian,Zhiqiang Dong,Maolin Fan,Jianchao Cai +7 more
TL;DR: In this article, an adaption model was proposed to describe the adsorption behaviors of CH4 and CO2, and the thermodynamics parameter of adsoverage was obtained, and then the influence of mineral composition and pore structure on the adsoption characteristics of CH 4 and CO 2 in shale was clarified.
Journal ArticleDOI
Effect of sub-/super-critical CO2 and brine exposure on the mechanical and acoustic emission characteristics of shale
Junping Zhou,Shifeng Tian,Lei Zhou,Xuefu Xian,Chengpeng Zhang,Kang Yang,Zhiqiang Dong,Zhaohui Lu +7 more
TL;DR: The effect of fluid-shale interaction on the mechanical behavior of shale is of great significance for the safety of long-term CO2 sequestration in shale formations in this paper.
