以达西定律渗流理论为基础,利用生产测井资料确定剩余油饱和度,根据相对渗透率与饱和度的经验公式,导出产层含水饱和度与产水率的函数关系。另外根据地区经验参数,制作含水饱和度与产水率的关系图版,确定剩余油饱和度。本方法在中原油田文13 块应用时取得了良好的效果,是油田开发中后期进行剩余油饱和度监测的有效手段。

The writer puts forward one method of calculating remaining oil saturation by making use of producing logging data.Based on Darcy’s law , the remaining oil saturation is obtained through function relationship between water saturation of pay zone and producing water ratio according to experience equation of relative permeability and saturation , We make relative figure of water saturation of pay zone and producing water ratio through region experience parameter. The good results are received by making use of the method in Wen 13 Block of Zhongyuan Oilfields , This method is valid measurement of inspecting remaining oil saturation at medium-term and later period of oilfield exploitation.
