摘　　要：现有的油水井修井措施后效益评价方法尚未形成一套系统、全面且精准的体系,难以全面考量修井措施后效益评价的复杂因素。为此,构建了一种基于层次分析-模糊综合评价的油水井修井措施后效益评价方法。首先,分析油水井修井措施后效益的影响因素,根据油田专家意见构建评价指标体系;然后,采用层次分析法确定评价指标权重,通过模糊综合评价法计算综合评价结果;最后,通过大港油田实际工程数据验证了该模型的有效性,为油田企业精准衡量修井作业效益、合理配置资源、优化修井策略、提升整体开发效益提供了理论支撑与决策依据。The current evaluation approaches for oil-wells in petroleum extraction have not formed a systematic and precise quantitative framework,so it is difficult to comprehensively consider the complex factors involved in post-workover effectiveness.This paper develops an effectiveness evaluation model for oil-water well workover measures based on the Analytic Hierarchy Process(AHP)and fuzzy comprehensive evaluation.First,the factors influencing the effectiveness of workover operations are analyzed,and evaluation indicators are selected to construct an indicator system.Then,the AHP method is employed to determine the weights of the evaluation indicators,and the fuzzy comprehensive evaluation method is used to calculate the effectiveness scores,thereby quantifying the evaluation results.Finally,the actual engineering data of Dagang Oilfield verifies the effectiveness of the proposed method,providing robust theoretical support and decision-making references for oilfield enterprises to accurately assess workover effectiveness,allocate resources rationally,optimize workover strategies,and enhance overall production efficiency.
