摘　　要：喇嘛甸油田断层发育,断层边部厚油层剩余油富集,主要利用水平井技术挖潜剩余油。但断层边部控制井点少、构造变化大、油层发育复杂,水平井轨迹优化设计难度大。为此,利用井震结合技术对断层区构造特征、油层发育状况进行准确预测,并以地震资料进行约束,开展三维地质建模,得出断层边部无井区域的构造,从而实现了断层区水平井轨迹空间位置、方位及水平段长度的优化设计。形成一套断层边部水平井轨迹优化设计方法,在喇嘛甸油田5口断层边部水平井设计及实施过程中得到了应用,平均钻遇率达到74.2%。LaMaDian oil field is fault development and remaining oil gathers in the thick reservoir at the edge of fault.Horizontal well is mainly applied to tap remaining oil.However,at the edge of fault,control wells are few,constitution change is great,and reservoir development is complex,which make the optimization of horizontal well track difficult.Therefore in this paper,well-seismic-based technology is used to predict the structural feature of fault zone and development status of reservoir.3d geological modeling is carried out based on seismic data and the formation of well-free region at the edge of fault is obtained.The optimization design of the location,orientation and horizontal section length of horizontal well track in fault region is achieved.Horizontal well track optimization and design method at the edge of fault is formed. This method is applied in the design and implement of five horizontal wells at the edge of fault in LaMaDian oil field,the reservoir-encountered rate reached to 74.2%.
