测试中非常规资料的解释方法

The Interpretation Methods of Unconventional Data in Testing

低渗透油气藏未达到径向流的测试资料,以及测试过程中出现关井操作失误的测试资料,采用常规或现代试井解释方法难以进行有效分析。经研究发现,用非常规解释中的恢复程度法进行分析,可有效缩短测压时间,获得较准确的地层压力和储层渗流参数,从而提高测压资料解释率15.31％。

By the conventional and modern well testing interpretation methods, it is difficult to availably analyze the testing data of non-reaching the radial flow in the low-permeability reservoir and the testing data by misplaying operation in testing process during the well shut in. In this study, the analysis of the retrieval present for the conventional interpretation methods may be available to reduce the time of testing pressure, acquired the accurate data of formation pressure and reservoir parameters, as a result it can increase the interpretation ratio of testing pressure data by 15.31 %.
