Abstract:
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 compli- cate 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.
