摘　　要：针对气田开发方案决策的复杂性和困难度,构建了组合赋权集对分析模型。该模型应用集对同一度概念构建气田开发各备选方案与理想方案的同一度,运用组合赋权法来计算各评价指标的权重,再运用线性加权法计算贴近度,对开发方案做出最终优选并应用于四川中坝M气藏。实例表明:模型计算结果符合客观实际,为气田开发方案的优选与评价提供了一种新的思路和方法。To make a strategy of gasfield development scheme is complicated and difficult.So,this study establishes a model of combination-weighting set-pair analysis to solve this problem.At first,this model applies a concept of set-pair identical degree to construct an identical degree between alternative scheme and ideal scheme;and then,the weight of every evaluation index is calculated by combination-weighting method;at last,the close degree is calculated by linear-weighting method to optimize the development scheme.This analysis is applied toZhongba M gas reservoir,Sichuan Basin.The calculated result from model is in agreement with real one.
