摘　　要：州57属于复杂断块薄互层油藏,区块断层发育、油水分布复杂、油水同层发育明显,对水平井的开发效果产生很大影响。以地质资料为基础,结合水平井实际生产数据分析出区块内油水同层分布规律,再利用数值模拟方法研究油水同层对水平井钻遇多层产水的影响,建立了相应的水平井产水率与含水饱和度解释图版,最后给出了油水同层区块水平井相应的开发调整技术对策。Zhou 57 is a complex block thin layer reservoir,block faults,water distribution complex and developing lots of oil - water layer,have a great impact on the development of horizontal well.With geological data,combined with the actual production data of horizontal well,we analysed the block distribution of oil and water layers,and then studied the relation between oil-water layer and the water production rate by using numerical simulation,established the appropriate level of water production rate and water saturation interpretation chart,finally gave the corresponding technological counter measures of horizontal well development adjustment in oil-water zone.
