摘　　要：断层附近油井的水力压裂措施可行性一直是许多科研工作者探讨的问题,有些科研工作者认为,对断层附近的油井实施压裂,一旦裂缝延伸至断层,将会造成支撑剂和压裂液沿断层流失导致压裂无效,或者引出断层水造成油井含水暴涨。通过对断层附近油井的压裂措施实践,认为断层不是制约压裂效果的绝对因素,并详细阐述了断层在油田开发及压裂措施中的正、反两方面的双重作用,给出了断层附近油井压裂的措施原则及措施时机,对断层附近油井压裂措施决策具有重要的指导意义。Performing hydraulic fracturing treatment near faults may cause fractures to extend into the faults, which results in the failure of fracturing treatment since the proppant and the fracturing fluid leak off into the faults, or results in water production's dramatic increase because the water in the faults flows into oil well. Through practicing fracturing treatment near faults, the feasibility of fracturing treatment near faults was studied, and the conclusion is drawn that fault isn't the main factor that affects post-fracture response. The negative and the positive effects of faults on the exploitation and the fracturing treatment are illustrated, and the principles and the optimum time of fracturing are presented, which will play an important role in the decision-making of fracturing treatment near faults.
