摘　　要：目前调剖措施选井中存在影响因素多、盲目性大等问题，并且在实际生产中某些参数难以录取，若仍采用常权方法决策，会使决策结果不合理，为此，引入了基于变权的模糊层次分析法。在0．1～0．9标度的基础上量化调剖措施各评价参数，建立模糊一致矩阵，结合最大隶属度原则，优选出不同区块各评价参数的隶属度，最后将这些隶属度值组合得到各评价参数对最终结果的评价结果。该方法结合了定性和定量分析，消除了专家权重分配困难的缺陷，克服了在某些参数缺少时用常权方法决策不合理的缺陷。实例分析结果表明，该方法可降低调剖井选择的盲目性，使决策结果更加科学合理，具有较好的推广应用价值。Current profile control well selection has many influence factors and blindness problem,and some parameters are hard to record during actual operation.Constant weight method will lead to irrational result.Hence,fuzzy analytical hierarchy process on variable weight basis has been introduced.Each evaluation parameter of profile control is quantified based on 0.1～0.9 scale,fuzzy consistent matrix is established,the subordinate degree of each evaluation parameter of different block is optimized according to maximum subordinate degree principle,and these values of subordinate degree is finally combined to obtain the final result of each evaluation parameter.This method combines quantitative and qualitative analysis,eliminates the difficulty of expert weight distribution,and overcomes the drawback of constant weight method when lacking of some parameters.Case analysis result shows that this method can reduce the blindness in profile control well selection,make the decision result more scientific and reasonable,and is worth of spreading.
