Abstract: 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.

摘要： 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.
