摘　　要：油田开发效果评价在提高油田管理水平、发现油田开发中存在的问题,以及提出调整对策和潜力评价等方面发挥着重要作用。模糊综合评价方法的引入,有利于提高油气田开发效果的分析水平,但指标隶属度、指标权重等确定方法仍需进一步发展和完善。研究认为:通过指标测度函数建立指标的隶属度矩阵较之传统方法更能够反映出不同评价单元的区别;结合灰色关联分析法和相似权法确定指标权重,可以最大限度地减少人为因素干扰,得到科学客观的权重结果;置信度概念的引入,能够使最终评价结果更好地反映油田实际开发水平。详细介绍了模糊综合评价方法进行效果评价、指标隶属度和权重的建立原理、方法和步骤,以新疆砾岩油藏为例进行了应用。Oilfield development effect evaluation played an important role for improving the management level of oilfields,finding out problems in oilfield development,proposing countermeasures for oilfield adjustment and analyzing development potential.The introduction of comprehensive fuzzy evaluation method was beneficial for enhancing the effect evaluation of oil and gasfield development,while establishment of subordinate index,the index weights and other aspects still needed for further development and improvement.The study indicated that compared to traditional method, the subordinate matrix established by measuring function can reflect the difference between different evaluation units. The index weight was determined in combination with the grey correlation analysis method and similarity weight method,it could minimize the interference of artificial factors,and the more scientific and objective index weight would be obtained.Actual oilfield development level can be better reflected by introducing the concept of confidence level.The principle and steps on fuzzy evaluation method,subordinate degree and index weight are introduced in detail.The method is used by taking conglomerate reservoirs in Xinjiang Oilfield as example.
