摘要

用模糊综合评判法进行了CO2吞吐选井选层研究,先运用统计学的方法和现有的CO2吞吐理论作了选井选层的单因素影响分析;然后以单因素分析为基础,确定了合理的隶属度的计算方法;最后通过求解模糊综合评判的反问题求得合理的权重,建立了完整的综合评判模型。实例分析得出的结果和现场实际一致,表明该方法是正确可行的,具有一定的推广价值。

Abstract

Fuzzy integrated evaluation is used to select wells and layers for CO2 Puff 'n' Huff. Firstly, the method of statistics combined with current theory about CO2 Puff 'n' Huff is applied to analyse effect of single factor to selection of wells and layers, secondly on the basis of the factors analysis, the calculation method of degree of membership is confirmed, thirdly, the converse of fuzzy integrated evaluation is solved and reasonable weights are acquired. So the complete model of integrated evaluation is constructed. the results from example analysis is consistent with field practice, which indicates that the method in this paper is right and it is worthy of diffusion
