| 摘 要： | 目前地层压力是气田开发中一项必不可少的数据,它是气藏能量的直接表现。目前,主要利用关井测压来获取目前地层压力,但是在生产任务重的情况下,没有条件采用较长时间关井获取目前地层压力,这是我们需要解决的一个问题。本文基于气藏气层中流体的渗流理论,只通过井底流压-产气量数据利用线性回归法,有效地解决这一问题。

| Abstract: | Present Formation Pressure (PFP) is a requisite data in development of gas field。PFP usually can represent energy of a gas pool。Recently, PFP is obtained by shutting in pressure test。In some cases ,it is impossible that gas well is closed in because of consumer's demand for gas。We must find a method, that it can help us to obtain PFP。The paper can tell us to obtain PFP by a new and original method。The method based on fluid flow through porous medium theory, it can accurately calculate PFP by a batch data of bottom hole flowing pressure an flowing rate。 |
