摘　　要：在开发过程中浅层稠油易发生地表窜漏,不仅会污染环境,而且会影响油田产量。若对所有窜漏相关井进行封堵,不仅封堵施工量大,而且会破坏储层物性,降低储层动用程度。为解决地表窜漏问题,油田开展了大量的现场试验,总结出地漏治理的技术路线为:先确定窜漏相关井,再综合电法监测结果、地质分析和生态动态数据分析确定窜漏通道,最后选择窜漏直接相关井和窜漏通道上的关键节点井进行封堵施工。应用结果表明:与直接对所有窜漏相关井封堵相比,该方法不仅可以消除地表窜漏,而且治理成本更低,可为解决类似地表窜漏提供借鉴。Shallow heavy oil is prone to surface leakage in the development process,which will not only pollute the environment,but also affect oilfield production.If all leakage-related wells are blocked,not only a large amount of plugging works will need to be done,but also the physical property of the reservoir will be damaged and the degree of reservoir utilization will be reduced.In order to solve the problem of surface leakage,a lot of field tests have been carried out in oilfield,and the technical route of surface leakage control has been summarized as follows:firstly,the channel-to-leakage related wells are determined,and then the leakage channel is determined by synthesizing the electrical monitoring results,geological analysis and ecological dynamic data analysis;finally,the wells directly related to the leakage channel and the key node wells on the leakage channel are selected for sealing construction.The application results indicate that this method can eliminate the surface channeling leakage as well as reduce the treatment cost compared with the direct blocking of all leakage-related wells.This provides reference for solving similar surface leakage.
