Abstract:

Drillers, waiting-and-weighting and circulating-and-weighting techniques are commonly used kill well methods in oil fields. On the basis of principles of fluid mechanics and conditions of kill well, the rules of casing s pressure and stand pipe s pressure are analyzed, and the unified model has been set up, which is of the advantages of compatability, accuracy and programing. The unified model is not only conveniently used in oil fields, but lays the theoretical foundations for kill well simulators as well.
