Abstract

Abstract

Tectonic stress action is one of the few effective over-pressuring mechanisms in many existing over-pressuring mechanisms. Therefore, a vertical three-dimensional tectonic stress section passing Kala 2 gas pool is simulated. The results show that there is about 10 MPa stress concentration at Kala 2 reservoir structural part, and that there is about 50 MPa that is caused by tectonic stress action in the overpressure of Kala 2 gas pool, and the rest by other over-pressuring mechanisms. This research has significance for reasonably assessing and developing gas pool.
