摘　　要：哈得油田石炭系中泥岩段薄砂层油藏为埋藏深、厚度薄、受岩性控制的层状边水未饱和油藏,采用以地质导向为基础的双台阶水平井钻井技术。为了对双台阶水平井钻井质量进行有效评价,引进了一套完善的双台阶水平井钻井实时跟踪系统。该系统充分结合导眼井及邻井的地质、钻井、录井、测井及随钻测井等多种资料,实现双台阶水平井钻井的实时跟踪,对井眼轨迹位移及钻遇地层进行实时分析,计算钻遇率。以哈得油田某井区双台阶水平注水井HD10-HX为例,详细介绍了该井实时跟踪分析。The Carboniferous thin sand layer in mudstone section was the deeply buried and thin laminar edge-water reservoir in Hade Oilfield which was controlled by lithology,a double-step horizontal well drilling technique based on geologic steering was used.For effective evaluation of the drilling quality of double-step horizontal wells,a set of drilling real-time tracking systems were introduced.The system fully combineed with the data of geology,drilling,mud logging,wireline logging and well logging while drilling from pilot holes and adjacent wells in the block.a real-time analysis was carried out on the displacement of borehole and strata encountered in drilling,the target drilling ratio was calculated,the drilling of double-step horizontal wells could be real-time tracked.The system is firstly applied in HD10-HX Well,which is double-step horizontal water injection well,favorable results are obtained in practice.
