摘　　要：针对中原油田在小井眼开窗侧钻井中井漏、卡钻事故发生频繁的问题 ,结合小井眼侧钻井及中原油田油气层的特点 ,分析了小井眼侧钻井井漏、卡钻的原因 ,从钻井液性能控制和钻井工艺方面采取了适应于侧钻井的防漏防卡措施。经在中原油田不同区块的多口侧钻井实践证明 。The accident of lost circulation and sticking are very frequent in slim hole sidetracking of Zhong-yuan Oilfield.On the basis of the characteristics of Zhongyuan oil reservoir,the paper analyses the reasons of lost circulation and sticking in slim hole sidetracking, and proposes the measures of antileakage and sticking prevention from controlling drilling fluid performance and drilling technique etc.aspect.Through field application in sidetracking wells in Zhongyuan Oilfield,these measures have better effect to prevent lost circulation and sticking.
