不关井求气层平均地层压力的方法

OBTAINING AVERAGE GAS RESERVOIR PRESSURE WITHOUT SHUTTING IN WELM

本文从气井的经验产能方程出发,推导出了导数产能方程,用以确定气井的平均地层压力,从而解决了不关井确定地层压力的问题,并给出了计算实例。

<ABSTRACT> Starting from the equation of empirical productivity of gas wells, this paper deduces the equation of derivative productivity, which is for determining the average forma-tion pressure of gas wells, thus the determination can be done without shutting in the well. Calculation examples are also given.
