Abstract
Putaohua oil layer is the main target layer in gulongnan area. The reservoir is mainly sheet sand with thin thickness, heavy mud content and poor physical properties. In recent years, the development effect of different blocks in this area is quite different. In this paper, the reservoir heterogeneity in Gulongnan area and each block is studied to provide reliable geological basis for improving oilfield development effect. Through the analysis of intra-layer, inter-layer and plane heterogeneity, it is considered that the overall reservoir heterogeneity in Gulongnan area is strong. In terms of deposition units, the heterogeneity of PI1, PI3 and PI6 is relatively strong, while the heterogeneity of PI2 and PI7 is relatively weak, and the remaining units are in between. In terms of zoning, the heterogeneity in G6 block is weak, the heterogeneity in M1 and A1 blocks is strong, and the heterogeneity in D1 block is the strongest. The application of heterogeneity analysis results provides strong support for promoting oil well effectiveness and delaying water breakthrough time.
