ABSTRACT

The main reservoir stratum of shale gas in the Jiaoshiba area, Sichuan basin is Wufeng-Longmaxi Formations. This paper calculates the tectonic difference stress values of JY1 well in different depths and numerically simulates the shale gas reservoir by elasto-plastic incremental method. The results of tectonic difference stress value suggest that the present tectonic stress values distribute strippedly in plane. The areas in favor of the development of fractures are stripped and mostly distributed in the northeast, middle and southwest of Jiaoshiba area, where the shale gas is concentrated.
