摘　　要：X区块在钻进过程井壁稳定性差,导致频繁的阻卡、井漏等复杂情况。本文从复杂情况统计分析入手,根据测井资料分析了该区块部分井的井径扩大率,结合地层的理化试验为基础,分析总结了X区块钻井复杂情况的根本原因,为今后该区块及邻近区块高效钻进提供参考与借鉴。In the drilling process of X area, the borehole stability is poor, which often leads to blockage, leakage and othercomplicated problems. In this paper, based on analysis of complex condition statistics, well hole enlargement ratio of this area wasanalyzed according to the well logging data, and combined with rock mechanics and chemical test, the primary causes of complexdrilling conditions in X area were analyzed and summarized, which could provide the basis for the safe and efficient drilling in thefuture.
