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。
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.
