M地区水淹层含水饱和度的计算

The calculation of water saturation in water flooded layer on M region

以M地区测井、实验、试油等资料为研究基础,采用电阻率相对值技术,建立含水饱和度解释模型,避开了地层混合液电阻率的求取.探讨了研究区两种含水饱和度计算方法的应用过程,计算结果表明电阻率相对值法计算的含水饱和度与岩心分析饱和度匹配较好.实际应用表明,该模型效果良好,为M地区饱和度计算提供了一种行之有效的方法.

Based on the well logging,experiment and test oil data, we established interpretation models of water saturation using the relative resistivity technology, and then avoided calculating resistivity of mixed fluid. This paper discusses two methods of water saturation calculation and the result from the method of relative resistivity is consistent with that of core analysis. The actu al application proves that this model is good, which provides an effective method for the satura tion calculation on M region.
