A METHODOLOGICAL APPROACH FOR RESERVOIR HETEROGENEITY CHAR ACTERIZATION OF QIULIN OIL FIELD USING ARTIFICAL NEURAL NETWORKS

Porosity and permeability are the best show of reservoir heterogeneity which is because of the heterogeneity and nonliner spatical distribution of the rocks.In recent years,there is a wide application of ANN in reservoir description and more application can be found in using ANN to choose exact reservoir model for well test.This paper suggested an ANN-way to descripe reservoir heterogeneity and to build a rather reliable interpretation model of porosity and permeability.Also,by this way,a study was done to reservoir physical properties in Sanjianfang Formation,Qiulingoil field.
