摘要:

本文分析了井内温度、环空岩屑含量、波动压力及环空压降等对井内泥浆液柱压力的影响,分别介绍了它们的计算式,得出了正常钻进和起钻时不致反失井涌的合理泥浆比重计算式,并编写了适用于PC一1500计算机的电算程序。

Abstract: The influence of borehole temperatuer, drill cuttings, surge pressure and annular pressure drop on the effective static bottomhole pressure of drilling fluid is analyzed in this paper. Their calculation formulas are introduced during drilling and tripping operations is discussed, and its calculation formulas are derived. The calculation program used for PC-1500 computer is also compiled.
