摘要：

本文提出了一种对任意形状有界地层内一口长时生产井的短期压力恢复数据处理分析方法。该法的理论基础既不同于传统的Horner分析法,又不同于现代试井图版分析法,它是在考虑了关井前地层中实际流动状况下推导出来的,因而,分析处理该类问题试井资料的结果更符合实际。使用该法可求得地层流动系数,单位压降地层弹性储量以及井壁污染系数。实际资料的处理证明了该法对有界地层内一口长时生产井的短期压力恢复数据处理极为有效。

Abstract:

This paper presents a method of analysing short buildup data after longtime production in a well inside a finite reservoir with any shapes. The basic theory of the method is different from both traditional Horner method and Modern type curve analysis method. It is derived from considering the actual flow conditions in the reservoir before shut-in. Therefore, ther esults of analysing short buildup data by this method coinside more closely with actual values. Its validity is verified through analysing short b buildup data after longtime production in the finite reservoir in situ.
