摘　　要：本文根据埕岛油田馆陶组油藏压力衰竭和海水钻井液密度高的实际情况 ,提出了防止压差卡钻问题 ,进而分析了压差卡钻的影响因素 ,通过分析找到降低压差卡钻趋势的可控因素 ,对如何改变这些因素来减少压差卡钻可能性做了一些实验研究 ,最后为该区的防止压差卡钻提出了一些建议。In this article,the problem about preventing differential pressure sticking is proposed according to the practical situation of high density of seawater drilling fluid and pressure declining reservoir of Guantao group for Chengdao Oilfield.Through analyzing the influencing factors of differential pressure sticking,the controlling elements are found to reduce the tendency of differential pressure sticking.Some experiences are accomplished for changing these factors and decreasing the possibilities of differential pressure sticking.At last,some proposals are put forward for preventing differential pressure sticking in this area.
