摘　　要：塔里木盆地库车山前构造地质情况和钻井情况复杂,导致钻井过程中井漏频繁发生,钻井液损失量大,造成巨大的经济损失。通过统计库车山前区块漏失情况,分析盐膏层及目的层漏失特征,揭示了库车山前地区盐膏层与目的层钻井液漏失机理,明确了盐膏层及目的层钻井液漏失成因,形成了堵漏基本原则和治漏技术思路,对今后库车山前地区的防漏堵漏工作起到重要的指导意义。The Tian Mountain Front Block in North Border of Tarim Basin is very complicated,and downhole losses are easily encountered in the process of drilling operation,so the loss amount of drilling fluids is enormous,resulting in huge economic losss.Based on the leakage in the Tian Mountain Front Block,the characteristics of thief zones were analyzed,and the leakage mechanism of drilling fluids was revealed,and the basic plugging principle and lost circulation control technique solution were prospected.The paper can play an important role in the plugging operation in the Tian Mountain Front Block in the future.
