摘要/Abstract

摘要： 压降曲线的拟稳定阶段是矿场不稳定试井的一个重要阶段,通常用于预测油和气藏的地质储量。本文对拟稳定阶段关系式进行了系统推导,并提出了判断拟稳定阶段的不同方法。

关键词: 压降曲线, 压力动态, 拟稳定阶段

Abstract: The Pseudo—Steady—State of pressure drawdown curve is an important stage of transient wcii testing. It is usually used to predict reserves of oil and gas reservoirs. The relationship of the Pseudo一steady 一state stage is derived judging methods are presented in this paper.

Key words: pressure drawdown curve, pressure behavior, pseudo一steady—state stage
