Daqing Oilfield has entered the development stage of high water cut later stage, the contradiction between inter layers and interior layers is more prominent, the rate of water injection pass rate decreases rapidly, the manual test workload is huge, the existing test team can not meet the requirements; at the same time, the existing high-efficiency measurement and adjustment technology cannot provide Continuous monitoring data and real-time dynamic adjustment of downhole injection volume, for this purpose, Daqing Oilfield carried out research and research on cable-controlled intelligent layered water injection technology. The technology is mainly composed of two parts: underground cable-controlled intelligent water injection technology pipe column and ground wireless remote control system. It can realize real-time monitoring and control of underground stratified flow and pressure in the office, realize online inspection, automatic measurement and adjustment, and report output. With the function, 30 wells were tested in the field and achieved good results. This technology is a continuous, efficient and real-time new generation water injection technology.
