摘要
对于低阻油气藏,常规测井解释方法计算的含水饱和度有时不符合地层的实际含油情况,而在没有油基泥浆取心的情况下,要得到油藏原始含油饱和度往往很困难。本文通过J函数建立含水饱和度与毛管压力之间的联系,从而求取油藏的原始含油饱和度。该方法在Y油田取的了较好的应用效果。
For low-resistivity reservoirs,the water saturation calculated by conventional logging interpretation method sometimes does not agree with the actual oil bearing condition. It is difficult to get the initial oil saturation without oil-base mud coring.The paper presents a method to get the initial oil saturation through establishing the relationship between water saturation and capillary pressure by J function.This method has achieved favorable effect in Y oilfield.
