Optimizing Potential Condition of Weixing Oil Field Low Well with the Method of Fuzzy Comprehensive Evaluation

During the process of the super high water cut,low production and low efficiency wells has a rising trend year by year.How to identify low production and low efficiency wells has become an important issue for the efficient development of the oil field.In this paper we use the analytic hierarchy process(fuzzy mathematics) and system engineering principle, considering the complexity and not balanced factors which affect the oil wells.According to the various factors at different influence degree level to classify,and then to determine the weight of each factor,we form a set optimization fuzzy comprehensive evaluation method of low production and low efficiency.Through analysis of living example,it is shown that it is an objective and effective method which is convenience to calculate and easy to manipulate and popularize.
