# 基于J函数的含油饱和度建模方法—以陆丰A油田为例Modeling Method of Oil Saturation Based on J Function—Taking Lufeng A as an Example

Abstract: With the development of water injection, the parameters of the reservoir change accordingly. Because of the influence of flooding, there is a significant difference between the oil saturation of logging interpretation and the original oil saturation of reservoir, and it cannot represent the original distribution of oil reservoir. According to the average capillary pressure curve, the original oil saturation of each type of reservoir is calculated by flow unit, and a model of oil saturation based on J function is established. The error of oil saturation in logging interpretation at different drilling periods is reduced. Therefore, this work is important for reserves recalculation and reservoir numerical simulation.
