Abstract

Abstract: There has been complex structural deformation in Pengshui Area of southeast Chongqing since Mesozoic and Cenozoic. The direction of paleotectonic stress field and tectonic evolution sequence are analyzed in detail, and the quantitative characterization of ground stress is of great guiding significance for the exploration and development of shale gas in Pengshui Area and even in southeast Chongqing. Through analysis and treatment of joint and fault striations in Pengshui Area and its periphery, combined with homogenization temperature of inclusions and apatite dating method, the evolution of paleotectonic stress field in Pengshui Area was reconstructed. Abaqus software is used to quantitatively calculate the stress value of paleotectonic stress field in Wufeng—Longmaxi Formations shale reservoir. The results show that Pengshui Area in southeastern Chongqing mainly experienced two stages of tectonism. In the Middle Yanshan period, it was gradually expanded by SE—NW in Jiangnan uplift. In the Late Yanshanian—Himalayan period, the uplift of Qinghai—Tibet Plateau caused NE-trending compression in Pengshui Area. The numerical simulation of tectonic stress field shows that the high value areas of maximum principal stress are mainly distributed in syncline core, end of fault zone, fault intersection. Stress numerical simulation is the basis of fracture development and deep fracturing research, which can effectively improve the success rate of drilling.

Key words: numerical simulation of tectonic stress field, tectonic evolution sequence, Wufeng-Longmaxi Formations, shale reservoir, Pengshui Area
