摘　　要：由于特殊的地层压力造成较窄的钻井液密度窗口、长节流管线产生较大摩阻、低温环境对井控过程压力变化和压井液流变性的影响等因素,使深水井控更加复杂。文章简要介绍司钻法压井,并以司钻法压井在深水"下喷上漏"地层压井的成功实例为基础,简要剖析井下复杂情况发生原因、司钻法压井处理过程及由此得出对井控方面的认识,对司钻法在深水井控的应用具有一定指导意义。Since special formation pressure causes a narrower drilling liquid density window,the long joint pipeline produces a larger cryptographic,low temperature environment on the effect of pressure changes in well-controlled process and the fluid flow rate,so that deep water well control is more complicated.This paper briefly introduces the drilling of the driller-method,and the successful example of the driller-method in the deep water“spray leakage”formation,briefly analyzes the cause of the underground complexity,the drilling pressure treatment process as well as the understanding of well control,and the application of the driller-method has certain guiding signif icance in the application of deep water well.
