油田进入开发中后期低效井呈逐年上升的趋势，低效井综合治理工作是油田需要开展的主要工作，如何保证低效井的治理具有效益是老油田开发面临的主要问题。为了提高低效油井的治理效果和老油田开发整体效益，以油田单井效益评价系统为依托，从单井入手，探索适合低效井治理效益潜力的评价标准、方法与指标体系。通过低效油井治理效益潜力评价体系的构建，采用模糊综合评价对57口低效油井进行效益潜力综合评价，降低了油井治理措施实施的风险，提高了低效油井治理的成功率和治理效果。现场实际应用表明，模糊综合评价可以提高油井效益潜力评价的客观性、准确性，具有较强的实用性和可操作性。

In the middle and late stage of oilfield development, the number of low efficiency wells is increasing year by year. The comprehensive treatment of low efficiency wells is the main work to be carried out in the oilfield. How to ensure that the treatment of low efficiency wells is effective is the main problem facing the development of old oilfield. In order to improve the treatment effect of low efficiency oil wells and the overall development benefit of old oilfields, based on the evaluation system of single well benefit in oil fields, the evaluation criteria, methods and index system suitable for the treatment benefit potential of low efficiency wells are explored from the perspective of single well. Through the construction of the evaluation system of the potential benefit of low efficiency oil well treatment, the fuzzy comprehensive evaluation was used to evaluate the potential benefit of 57 low efficiency oil wells, which reduced the risk of the implementation of oil well treatment measures and improved the success rate and treatment effect of low efficiency oil well treatment. The field application shows that the fuzzy comprehensive evaluation can improve the objectivity and accuracy of oil well benefit potential evaluation, and has strong practicability and operability.
