摘要: 本文主要对发现溢流前一直有泥浆循环情况下的压井过程中套压和裸眼地层受力计算问题进行改进,建立了数学模型,并用它对司钻法压井的计算进行了研究,给出了与之有关的计算公式。研究表明,改进的计算方法较传统的“连续气柱”计算方法更接近实际。

Abstract:

This paper is mainly about the improvement on the killing well calculation of casing pressure at any depth in hole when there is always mud to circulate before the kick has been detected. By using the mathematical model derived, the calculation in Driller s method has been studied, and relative calculating formulas have been derived. It has been shown that the improved method will accord with the practice more than the conventional "continuous gas column" method.
