摘要
在松辽盆地嫩江沿岸钻井过程中经常遇到塌、漏、阻、卡现象，尤以青山口组的青２、３段问题突出，主要表现为：起钻遇卡不严重，但下钻遇阻严重，需划眼６～７ｄ．嫩８井采用具有封堵防塌能力的聚合物钻井液体系和相应的工程措施，顺利地钻达目的层，技术经济效益显著。
Some serious problems, such as collapse, leakage, resistance and sticking, were encountered during drilling in Nenjiang, SonliaoBasin. The polymer drilling fluids with capacity ofplugging and collapse prevention and correspounding engineering measures were applied in Nen WellNo. 8, which ensured the successful drilling to thetarget, and remarkable economic benefits.
