,distributions of sandbody,main current direction and waterflood front,as well as residual hydrocarbon saturation of sub-layer are qualitatively or semi-quantitatively analyzed.
针对井地电位测量取得的丘陵油田陵4块的实测电位数据,采用数值模拟和反演成像方法对实测电位数据进行了处理,得到了陵4块储层的电阻率分布,结合储层孔隙度、岩性和地层水矿化度等资料,利用反演电阻率对目的层注水前缘和剩余油气分布进行了定性和半定量分析。
