摘　　要：柴达木盆地油南构造地质情况异常复杂 ,井漏严重 ,通过重点预探井油南 1井的钻探实践 ,分析了油南构造钻井的漏失机理 ,认为油南构造上油砂山组 (N2 2 )地层裂缝发育 ,地层含盐量高溶解后易发生井漏 ,并且地层压力低。针对这些问题 ,总结出了一套在油南构造钻井的防漏堵漏技术措施 ,在油南The geology of Younan strucure in Caidam basin is very complicated, and lost circulation is serious. Field practice in Well Younan-1 indicate that loss circulation is caused by extensive rifts in the upper Youshashan Formation, and easily dissolved salt within the formation. A series of lost circulation control technique are summarized, which have been applied successfully in Younan structure drilling.
