摘　　要：MFE地层测试工具因其操作技术难度较大,使用范围一般控制在井斜45°以内,极大限制了其在测试工艺中的使用范围。在不断改进老式工具,优化工艺的基础上,结合近几年该工具在大量斜井中的使用经验,对MFE测试工具在大斜度井使用中的难点进行解析,提出了相应的解决措施。在晋古XX井施工中,针对该井测试层位上部有射开层的特殊情况,对井筒进行了通井和刮削,以及地层汲水实验等作业,采用相应的工艺和管柱,配置不同的工具,完成了测试施工任务。通过采取相应措施,拓宽了MFE地层测试工具适用范围。The application range of MFE formation testing tool is generally restricted within 45°due to its huge technical difficulty in operation,which greatly limits its application range in testing technology.In this paper,the application difficulty of MFE test tool in highly deviated wells is analyzed and the corresponding solutions are proposed by the combination of the application experiences in recent years and the improvement of the old tools and process.During the construction process of Well Jingu XX,drifting,scraping operation of wellbore and the formation water drawing operation were carried out considering the fracture of the reservoir above the target test formation.The test construction task is completed by using the corresponding process,pipe string and configuring different tools.By taking corresponding measures,the application scope of MFE formation testing tool is widened.
