The invention discloses a method for analyzing efficiency factors of an oil pumping well system. The method comprises the steps of determining influence factors; by calculating correlation degrees and weight coefficients of the influence factors, determining a correlation order of the influence factors relative to the efficiency of the oil pumping well system; determining evaluation indexes of an oil pumping well, and defining comparison references of the evaluation indexes; calculating membership degrees of the evaluation indexes corresponding to the influence factors; and by comparing the membership degrees and the corresponding comparison references, determining relationships between the corresponding influence factors and the efficiency of the oil pumping well system. According to the method, the influence of specific parameters on the efficiency of the oil pumping well system can be analyzed by determining the relationships between the specific influence factors and the efficiency of the oil pumping well system; and a quantitative evaluation index system for the influence factors influencing the oil pumping well system is established, so that the parameter adjustment and optimization of the oil well can be guided in site and the oil pumping system is finally enabled to run efficiently.
Description
technical field [0001] The invention relates to the field of petroleum exploitation, in particular to a method for analyzing efficiency factors of a pumping well system. Background technique [0002] The technology to improve the efficiency of the pumping well system can establish a pumping well parameter sensitivity analysis model from 22 parameters in three aspects: equipment parameters, working system and management factors. Through the system simulation optimization design method, according to the results of the parameter sensitivity analysis The optimal design of different equipment parameter combinations improves the efficiency of the pumping well system. [0003] At present, the system simulation optimization design method can predict the system efficiency of the design results, but there is no clear quantitative basis for system analysis and optimization design, and it is impossible to analyze the influence of specific parameters in the pumping system parameter combi...
