The Analytic Hierarchy Process for the Reservoir Evaluation in Chaoyanggou Oilfield

摘要

Reservoir evaluation is one of important contents in the reservoir study. This paper has adopted cluster analysis method to optimize evaluation parameters of low permeability reservoir and the analytic hierarchy process (AHP) to determine the weight coefficient. Moreover, this paper has made the reservoir comprehensive quantitative evaluation for low permeability reservoir of Chaoyanggou oil field. According to the cumulative probability curve, the evaluation results can be divided into three categories, which conform to the low permeability reservoir characteristics of Chaoyanggou oilfield. The method of reservoir comprehensive quantitative evaluation has solved the problems of single-factor classification evaluation that the evaluation result is not unique and provided favorable basis for low permeability reservoir evaluation of Chaoyanggou oilfield.
