摘　　要：油藏注二氧化碳驱是提高采收率的一种重要方法之一。在二氧化碳驱提高采收率中 ,对油藏进行适用性筛选评价可提高注二氧化碳的成功率和经济效益。对注二氧化碳驱替机理进行了研究 ,综合分析选择了多个油藏参数作为筛选油藏的综合评价参数 ,并给出了这些参数量化方法。引入了模糊数学中最新发展的模糊层次分析法(FAHP) ,成功建立了综合评价方法。实例证明了该方法的科学性和系统性 。Carbon dioxide miscible flooding is an important way for enhanced oil recovery.A suitable candidate of reservoirs for application of carbon dioxide miscible flooding processes can improve its successful feasibility and get more benefit.A new method of ranking reservoirs for carbon dioxide miscible flooding based on fuzzy analytical hierarchy process (FAHP) was presented.Seven characteristic parameters of reservoir for evaluating suitability of carbon dioxide miscible flooding were chosen as the evaluating factors.A way for getting the suitable fuzzy values of carbon dioxide miscible flooding using fuzzy mathematical method was presented.Application procedure of this method to carbon dioxide miscible flooding reservoir was verified in ranking several reservoirs of CO 2 displacement.The result indicates that this way can be used to determine the effect of reservoir properties of reservoir responsing to the carbon dioxide injection and can avoid some shortcomings in selection of reservoirs for applying carbon dioxide miscible flooding process.
