通过对周庄-宋家垛油田油藏微构造的研究, 对其进行分类, 形成了微构造油藏的一套滚动开发技术。根据微构造油藏依附于断层、含油层位多、空间位置错移的特点, 采用了打多靶定向井、侧钻井和控制射孔高度等特色技术, 对周庄-宋家垛油田微构造块进行了成功开发和挖潜, 证明了开发中后期油田仍有较大的开发潜力。

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.
