摘要
提出一种非常规井控工艺技术——动态密封挤入压井法,给出压井液密度、排量等参数的设计方法。设计中充分考虑钻柱以下井筒部分功能,在压井时将残余气体挤入地层,以此提高井筒的安全性。
The model developed in this paper,which is called ＂Dynamic Seal-bull heading＂,proposer the methods to measure the kill parameters such as kill flow rate,kill density and so on.The overall advantage of the method is that it should provide a more reliable and conclusive off-bottom kill,because the formation fluid will be forced back into the formation and the well completely will be filled with a kill density will be fluid.The result shows this method has great application value and provides a new way for well control operator.
