摘要
随着焦石坝主体区块页岩气开发不断深入,地层压力逐渐下降,压裂施工结束后在钻除可溶桥塞的过程中易出现砂卡钻塞管柱的情况,通过分析造成砂卡的原因,提出相应的预防措施,在现场推广应用,可以有效防止出现砂卡的情况。
With the further shale gas development in the major block of Jiaoshiba area,its decreased formation pressure resulted in drill string sticking due to sand jam while drilling soluble bridge plugs after a frac job.Through analysis of the causes of a sand jam,corresponding preventive measures are put forward to effectively control the sand jam.
