Abstract

Abstract: Paleo?uplifts are the major areas for petroleum exploration in Sichuan basin. Research on the structural configuration, formation and evolution as well as gas?controlled effect has great significance for petroluem exploration in northwestern Sichuan basin. This paper studied the distribution and evolution process of Jiange paleo?uplift using the geologic, geophysical and well logging data, combined with the sedimentary thickness of the Upper Triassic Xujiahe formation in northwestern Sichuan basin. The result shows that the paleo?uplifting process can be divided into three stages: the embryo stage (T3x1-T3x3), the mature stage (T3x4-T3x6), and the destruction stage (J1z). The Jiange paleo?uplift is of complete evolution cycle, the Xujiahe formation is of good soruce?reservoir?caprock assemblage, and the multistage tectonization?formed stratigraphic and lithologic traps are the favorable targets for petroleum exploration in northwestern Sichuan basin
