摘　　要：随着大庆油田进入特高含水开发后期,分注井数、层段数逐年递增,测试工作量大幅增加,测试能力已达瓶颈,测试队伍与测试工作量之间的矛盾日益突出。近年来,攻克了包括电动验封技术、电动投捞技术和电动验封测调一体技术的全电控测试技术,这些技术可实现分层注水井验封、投捞、测调工作全过程电缆直控、地面直读,使测试工作由机械方式向机电一体化转变,大幅度提高了测试效率。但在技术推广应用过程中,出现工具结构设计不合理、材质强度不够等情况导致工艺成功率较低。因此,攻关完善分层注水井全电控测试技术,通过对电动验封仪、电动投捞仪和电动验封测调一体仪的优化完善,进一步提高工艺成功率,累计开展现场试验318口井,节约了测试费用,具有良好的推广应用前景。As Daqing Oilfield enters the late stage of ultra-high water cut development,the number of injection wells and layers is increasing year by year,and the testing workload has increased significantly.The testing capacity has reached a bottleneck,and the contradiction between the testing team and the testing workload is becoming more and more obvious.In recent years,we have focused on fully electronic testing technology,including electric seal inspection technology,electric fishing technology,and integrated electric seal inspection,testing and adjustment technology.This technology can achieve the full process of cable direct control and ground direct reading for layered water injection well sealing inspection,fishing and testing work,transforming the testing work from mechanical mode to mechatronics integration,greatly improving testing efficiency.However,in the process of technology promotion and application,problems such as unreasonable tool structure design and insufficient material strength have led to a low success rate of the process.Therefore,we will address and improve the all-electric control testing technology for layered water injection wells.Through the optimization and improvement of electric sealing instruments,electric fishing instruments,and integrated electric sealing and testing instruments,we will further improve the success rate of the process.The total number of on-site tests we have conducted has reached 318,which has saved testing costs and has good prospects for promotion and application.
