摘　　要：为了寻求解决辽河盆地杜229断块超稠油油藏在开采过程中水侵严重影响生产的问题,通过研究该区块构造演化史,分析了断层在超稠油成藏过程中的作用,认为该区块的边界断层对油气成藏起侧向封堵作用,后期小断层使油藏复杂化。根据水性分析和示踪剂监测资料,推断水侵的主要原因是部分断层的不封闭。建议在以后超稠油开发生产中,生产井段要距不封闭断层70 m以上。In order to solve the problem that super heavy oil production is seriously affected by water invasion in Du 229 faulted block of Liaohe Basin, this paper studies the tectonic evolution history of this block, and analyzes the effect of faults in the process of forming heavy oil reservoir. The result shows that the border fault in this block plays the role of lateral obturation in forming hydrocarbon reservoir, the minor faults of late stage complicate the reservoir. According to the data of water quality and tracer monitoring, it is deduced that the main reason of water invasion is that a part of faults are unsealed. It is suggested that the production interval should be over 70 m from unsealed fault in the future super heavy oil development.
