THE RESEARCH OF FUZZY INTEGRATED EVALUATION METHOD IN WELLS AND LAYERS CHOICE FOR CO2 PUFF ''''N'''' HUFF
CO_2吞吐选井选层的综合评判方法研究

Fuzzy integrated evaluation is used to select wells and layers for CO_2 Puff 'n' Huff.Firstly,the method of statistics combined with current theory about CO_2 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.
