采用半解释法对井间示踪监测资料进行处理， 求解储层的剩余油饱和度。该方法取解析法和数值法的优点优化组合形成， 包括： ①依据数值法确定油层压力分布和流线分布； ②通过模拟产出浓度和实测产出浓度的自动对照，确定最符合实际地层的剩余油饱和度分布方案；③利用物质平衡方法确定其他参数；④利用解析法提供一个平均值， 作为物质平衡方法的基础或参考。对港东油田浅３ ９ 井组的动态资料及剩余油饱和度分析的结果表明， 应用该方法评价区块的剩余油分布是有效的， 该方法在注水开发区具有广阔的推广应用前景。
The semi-interpretation method is used to process crosswell monitoring data to solve the residual oil saturation in the reservoir. This method takes advantage of the combination of analytical method and numerical method to optimize the formation of the formation, including: (1) determining the pressure distribution and streamline distribution of the reservoir based on the numerical method; (2) determining the most appropriate actual formation by the automatic comparison of the simulated output concentration and the measured output concentration Residual oil saturation distribution scheme; ③ the use of material balance method to determine other parameters; ④ the use of analytical methods to provide an average, as the basis for the material balance method or reference. The results of dynamic data and residual oil saturation analysis of Sham 39 well group in Hong Kong East Oilfield show that it is effective to evaluate the residual oil distribution in this block by using this method. This method has broad application prospect in waterflood development zone.
