引言目前,地层测试工作已在全国的油田上推广,测试资料的解释方法也日趋完善,进一步的深入研究工作也正在进行中。前一段时间,笔者曾对压力导数的计算方法进行了一些探讨,本文主要是介绍一种计算压力导数的方法并总结前一段的工作。压力导数△P’是由1.Bourdet 等人提出的(其文章见 World Oil 1983年第五期和第十期)。根据关井测压力恢夏所得到的△P对应于△t的变化,按照一定的方法求出△P’,然后根据所求的△P’做双对数的△t与△P和△t与△P’△t(tp+△t)/tp 关系曲线
INTRODUCTION At present, the stratigraphic testing has been popularized in oilfields all over the country, and the interpretation methods of test data have also been improved day by day. Further in-depth research work is underway. Some time ago, I had some discussion on the calculation of pressure derivative, this article is mainly introduced a method of calculating the pressure derivative and summarizes the work of the previous paragraph. The pressure derivative ΔP ’was proposed by 1.Bourdet et al. (For an article see World Oil 1983, Issue 5 and Issue 10). According to the measured pressure back to summer Xia get △ P corresponding to changes in △ t, according to a certain method to find △ P ’, and then according to the required △ P’ do double-log △ t and △ P and △ t And △ P ’△ t (tp + △ t) / tp curve
