摘要
气井生产动态特征分析是气田开发过程中重要的基础工作。长期以来,动态分析方法在油气田产量预测、可采储量计算、地层参数的确定中得到广泛应用。为此,在调研大量国内外文献的基础上,系统介绍了传统的Arps、Fetkovich方法和现代的Blasingame曲线、Agarwal-Gardner(A-G)、规整化压力积分(NPI)方法的基本原理及适用条件,进一步对比了不同气井生产动态分析方法的优缺点。把握不同动态分析方法的原理及其优缺点,为气藏工作者选择合适的动态分析方法提供了依据。
Production performance analysis is an important foundation in gasfield development.For a long time,performance analysis methods have been applied widely to yield prediction,recoverable reserves calculation and formation parameters determination.This paper presents the basic principles and applicable conditions of two conventional methods named Arps and Fetkvoich,and other three modern methods including Blasingame Curve,Agarwal-Gardner(A-G) and Normalization Pressure Integration(NPI).Furthermore,the advantages and disadvantages of those methods used for different gas wells are compared.Their own principles,and advantages and disadvantages can be very helpful in selecting the suitable one for effective development.
