摘要
吐哈油田温西三块目前已经进入高含水开发阶段,自然递减居高不下,主要原因即剩余油分布分散、类型复杂。对此,文章从温西三块三间房组水淹前后储层特征对比分析入手,总结剩余油分布类型、形成原因及相应的测井评价方法,并利用不同方法求取混合液地层水电阻率,计算水淹后储层含油饱和度和产水率,进行平面展布分布规律研究,充分挖掘层内剩余油。该套方法在本油田新钻井中应用效果较好,在温西一块二次测井解释中也取得了较好的推广应用效果。
Tuha oilfield WenXi San Kuai has entered high water development stage at present,natural decline is high. The main reason is the dispersed distribution and complex types of remaining oil. To this,the article begin with the contrast analysis of before and after water- flooded reservoir characteristics of three rooms set in WenXi San Wuai,summary of remaining oil distribution types,formation causes and corresponding methods of logging evaluation,and then use different methods to calculate the mixture formation water resistivity,oil saturation after water flooding reservoir and water production rate. in the end,research the plane distribution in order to fully excavate remaining oil layer. The set of methods not only has abtained good application effect in the new drilling in this oil field,but also achieved good application effect in the secondary logging interpretation of WenXi Yi Kuai.
