中文摘要：

深水钻井中钻遇浅层流十分危险,动态压井钻井方法是处理深水钻井浅层流问题的一种有效手段。文中从原理、特点以及关键装备等几个方面对动态压井钻井方法进行了介绍,并结合工艺流程,通过理论分析,得到了钻井液密度、排量、混配比,钻井液需求总量以及泵压、泵功率等参数的计算方法。计算结果表明,对井底压力起主要作用的因素是密度,需要精确控制与混配,在相同压力条件下,先钻小尺寸的领眼容易在排量满足要求的条件下控制浅层流。

英文摘要：

It is dangerous to meet shallow gas during deep water drilling.It is an effective method to handle the problems caused by shallow flows with Dynamic Kill Drilling（DKD）method in a safe and successful offshore drilling operation.Basic fundamental,characteristic and key facilities of DKD are introduced.Based on the process of DKD and theoretical analysis,the computation method of hydraulic parameters are obtained that deal with kill fluid density,discharge rate,mixing ratio,total volume of mud,pump pressure,and pump efficiency et al.The results indicate that the key factor of bottomhole pressure is mud density,and pilot hole is important to control shallow flows without too large of mud flow rate.
