Abstract: Through strengthened research in microstructure and system atically classified the microstructure, a series of progressive exploration and development techniques are formed in complex fault block in recent years. According to the microstructure adhering to the fault and strata of abundant oil-bearing, some special techniques are used, such as directional drilling, sidetracking, and controlling the height of bore shooting. The conclusion is that Zhouzhuang-Songjiaduo oilfield still has great potential of development. The recent successful development of Zhouzhuang-Songjiaduo has confirmed this.
