摘要

压力直接影响到气藏的开发效果及动态分析,因此运用测试不准确的地层压力将会大大影响开发效果评价及动态分析。牙哈凝析气田采用循环注气部分保压方式开发,历年的压力监测资料表明压力解释结果异常,其采气井压力恢复测试的地层压力普遍高于注气井压降试井的地层压力,给动态分析带来了很大的困难。为了解决这个难题,通过现场测试资料的分析,运用试井基础理论,得出地层压力异常的原因是测试期间的井间干扰引起的;利用井间干扰理论,对其进行校正,得出较为可靠的地层压力,解决了该气田测试地层压力异常的疑惑,解决了地层压力异常的难题。

Abstract

The partial pressure maintenance is used to develop the Yaha ric h gas-condensate reservoir in Tarim Oilfield. In recent years, the test reporte s of pressure show that the reservoir pressure for interpretation of pressure bu ild-up test data is higher than that for interpretation of pressure
build-down test data. As a result, it is hard for reservoir engineeres to analy ze performance. Through analysis, The reason of this phenomena is got. On the ba sis of analyzing the test reportes of the Yaha gas-condensate reservoir, by the  theory of the well interference ,the testing pressures was revised in order to  get correct reservoir pressure. In this paper, the question of how to confirm,co rrectly, the reservoir average pressure of the Yaha  gas-condensate reservoir w as solved, effectively.
