和熵权法相结合的综合评价模型,确定包括注气井数量二注气井层位二注气井注气能力二系统单位电耗二机组效率等9个评价指标的综合权重,采用模糊隶属函数法对评价指标进行无量纲化处理得到各指标的标准评价值,并用线性加权法计算各方案总评分,确定出最优注气方案三笔者以国内某枯竭油气藏型地下储气库为例,对同一注气量工况下的各注气方案进行综合评价,实现储气库注气方案的优选三优选结果与现场使用方案一致三结果表明:层次分析法与熵权法结合使用兼具主观性和客观性,使得注气方案评价更加客观二准确二可靠,对地下储气库最优注气方案的确立提供了一定的借鉴作用三

Abstract :Aimin g at the p roblem of com p rehensive evaluation of g as in j ection scheme in under g round g as stora g e ,a com p rehensive evaluation model based on im p roved AHP and entro py wei g ht method is p ro p osed to determine the number of g as in j ection wells ,the de p th of g as in j ection wells ,g as in j ection ca p acit y ,s y stem unit p ower consum p tion ,unit efficienc y and so on.The fuzz y membershi p function method was used to obtain the standard evaluation value of each index ,and the total score of each scheme is calculated b y linear wei g htin g method ,to determine the o p timal g as in j ection p ro g ram.Takin g the g as stora g e of a de p leted g as reservoir in China as an exam p le ,the g as in j ection scheme under the same g as in j ection condition is evaluated s y ntheticall y ,to select the o p timal g as stora g e g as in j ection scheme.The results consistent with field show that the combination of anal y tic hierarch y p rocess and entro py method is sub j ective and ob j ective ,which makes the evaluation of g as in j ection scheme more ob j ective ,accurate and reliable and p rovides a reference for the determination of the o p timal g as in j ection scheme for un -万方数据
