Geology-engineering integrated reservoir connectivity quality intelligent evaluation method and system

Abstract

The present application provides a geological-engineering integrated reservoir connectivity quality intelligent evaluation method and system, relates to the oil and gas field development technical field, and the method comprises the following steps: S1: constructing a special evaluation parameter system of reservoir connectivity quality, comprising determining a preset influence factor set for evaluating the reservoir connectivity quality between injection and production wells, the set comprising geological static parameters and production dynamic parameters; S2: multi-source data acquisition and targeted preprocessing, comprising acquiring actual data of each factor in the influence factor set of the target injection and production well group, and standardizing and preprocessing the actual data; S3: dynamic weight calculation based on the analytic hierarchy process, comprising determining the weight vector of each factor based on the influence factor set by using the analytic hierarchy process; S4: establishing a membership function library supported by geostatistics; S5: generating a fuzzy relation matrix; S6: executing fuzzy comprehensive evaluation and result quantization. The system is used for realizing the above method, and the present application is used for realizing the rapid, intelligent and quantitative evaluation of the connectivity between injection and production wells.
