早期试井分析的新方法

A NEW METHOD FOR THE INTERPRETATION OF EARLY PERIOD WELL TESTING DATA

常规试井和现代试井分析方法只成功地处理了中期试井资料,对早期试井资料的分析往往是失败的。本文提出一种新方法,将最优化和灰色系统方法成功地用于均质、非均质油气藏和DST中,所解释的Kh、S值和中期试井结果一致。从而使大量抛弃的早期资料重新变为丰富的信息。

Conventional and modern well test analysis methods are successful only in the interpretation of the middle period of well testing data, but they fail to analysis the early period data. By a combination of optimization and grey—system theories a new method is proposed in this paper which is successful in the interpretation of early period well testing data from a heterogeneous reservoir and also for those data from DST. The value of Kh and S obtained agree fairly well with those obtained by using mid-dle period data. Thus, a large quantity of data is restored which has been discarded earlier to get useful informations.
