Abstract: In order to improve the effect of separate water injection and the efficiency of testing，and reduce the volume of testing and adjustment jobs，cableless intelligent separate injection technology has been applied in Subei Oilfield for testing. This technology realizes remote cableless control for downhole intelligent water allocator，makes real-time and accurate testing and adjustment for separate water injection volume，and monitors separate injection pressure and other downhole data and parameters in real time，eliminating the job of running in instrument for testing and adjustment required by traditional concentric separate injection technology. The use of Y341 water injection packer，which allows backflushing of well，and inner anticorrosive coated tubing provides high reliability for the cableless intelligent separate injection string. The field testing in well N2-19 is successful with satisfactory application effect. The technology is worth spreading.

Key words: cableless intelligent separate injection, intelligent water allocator; real-time monitoring, internally-coated tubing

摘要： 为提高注水井的分注效果及测试效率，减轻测调工作量，在苏北油田试验应用了无线智能分注技术。该技术可实现远程无线控制井下智能配水器，对分层注入量进行实时准确测调。同时可实时监测分层压力等井下数据参数，省去了传统同心分注技术的下仪器测调施工。选用可反洗井的Y341注水封隔器和内防腐涂层油管，使无缆智能分注管柱具备较高的可靠性。在N2-19井成功进行矿场试验，取得较好的应用效果，具有一定的推广价值。
