【摘要】 为了判别疑难及复杂储层产液性质 ,研究了一种基于油水相对渗透率分析技术识别油水层的方法 .该方法以不同润湿岩石、不同性质原油的相对渗透率为基础 ,采用热解分析技术确定含油饱和度 ,对比分析不同润湿性、不同孔隙度储层共生水和残余油的含油饱和度 ,并与所建立的油水层解释标准对比 ,即可判别储层产液性质 .应用该方法试油测试了海拉尔和延吉盆地的 2 1口井 6 4层 ,符合率为 95.3% .结果表明 ,该方法适用于油气水分布关系复杂、难以用常规方法识别产液性质的储层更多还原

【Abstract】 A new method that distinguishes oil layer, oil-water layer an d water layer based on relative permeability analysis technique is given in orde r to identify producing fluid property in the complicated reservoirs. By relativ e permeability analysis technique that difference humidity of rock and differenc e kinds of crude oil, involved in pyrolysis analysis result in oiliness saturati on, evaluating saturation of residual-oil and water together that difference hu midity of rock and difference porosity layer exist, interpretive standard for oi l bed, oil-water bed and water bed is established to identify of producing flui d property in the reservoirs. 95.3% of interpretive obtained from 64 layers belo ng to 21 wells in Hailaer oil field and Yanji oil field. The method provides the best foundation for improving the comprehensive interpretation and evaluation l evel.更多还原
