Prediction of the Favorable Area for the Development of Fracture in Mud-Shale of Wufeng-Longmaxi Formation in Jiaoshiba Area, Sichuan Basin ()
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.
