摘要

///Tongcheng fault is a second class fault which controlls the development of Tongcheng structural belt in Jinhu sag. It is divided into two parts by its faulted feature showing reverse fault character at the south part and normal fault feature at the north part. There are different views about its character and evolvement. Tongcheng fault is considered as a typical strike-slip fault based on the structural analysis of seismic profiles. Varied directions of dip result in normal fault and reverse fault alternatively occurring along the fault because of strike-slip movement. Tongcheng strike-slip fault can not only form different types of traps, but also improve physical property of low-permeability reservoir, which is of great advantage to oil and gas accumulation.
