简介：Hutubi()井块DX12的河水库是在构造背景下面的一座lithologic烃水库。在这个区域的主要的含有石油的沙身体是薄的并且有一个差的横向的连接。因为油水关系的复杂性，油水库介绍一个低抵抗力特征，它把大困难带到烃水库鉴定。这篇文章开发能满足很好记载评估的低抵抗力水库的要求的井木头解释的一个有效方法。作者联合油水库地质学特征，记载曲线特征的油井和为低抵抗力分析原因的化学分析数据，然后建立适当水库参数解释模型，它使用不同浸透计算方法根据不同的代。当泥土内容是超过5%时，我们选择W-S双水模型；当页岩内容是超过13%时，我们使用Schlumberger公式；当页岩内容不太当时是13%时，我们使用高射炮公式。低抵抗力水库的好记载评估方法被被渗透，孔，毛孔结构的系数和页岩建立的无法缩减的水浸透公式改进了记载方法的内容，烃水库识别图表，和非抵抗力(重复形成测试(RFT)；模块化的动态测试(MDT)，等等)。为记载综合解释的井的这安排的巧合率在井块DX12是82.6%。它是为低抵抗力井木头解释的一个强大的方向。
