Application of Fuzzy Mathematics Evaluation Method in Prediction of Comprehensive Efficiency of Low Efficiency Oil Wells

Abstract

In the process of oilfield development, due to long-term continuous mining and changes in geological conditions, oil-inefficient wells will be gradually produced. This phenomenon is unavoidable. How to optimize the low-efficiency oil wells with comprehensive mining potential according to the actual development situation, so as to achieve effective treatment of low-efficiency oil wells, this approach is of great significance to ensure and improve the overall economic benefits of the oilfield. In this paper, the fuzzy mathematics method and the statistical weighting theory are used for comprehensive analysis. The weight of the evaluation index is predicted by determining the comprehensive adjustment potential of the low-efficiency oil well, and then the low-efficiency oil well comprehensive adjustment potential prediction evaluation model and method are established, and then the practical application is carried out. The method can provide a basis for judging the comprehensive adjustment measures for the development of low-efficiency oil wells in oil fields.
