Study on Reservoir Heterogeneity in Block S

Abstract

Based on core analysis and testing and logging interpretation data, this paper studies the interlayer heterogeneity and plane heterogeneity of the reservoir, and establishes a set of evaluations for calculating the interlayer and plane heterogeneity of Fuyang oil layer. Standard, draw contour maps of 5 parameters and 12 main force layers. The results showed that 77% of the small layers with interlayer heterogeneity showed strong heterogeneity, and 23% showed moderate heterogeneity or homogeneity. 80% of the plane heterogeneity of the small layer is strong heterogeneity, and 20% is strong heterogeneity.
