Cable digital layering injection ground control system

The invention provides a cable digital layering injection ground control system. The system comprises an oil pipe and a cable digital water distributor connected to the oil pipe. The cable digital water distributor is electrically connected to a ground controller on the ground through a cable. The ground controller is electrically connected to a host computer. The cable digital layering injection ground control system can automatically adjust injection volumes for all layers, can monitor and store downhole pressure, temperature and flow parameters in a real-time manner, and can automatically perform downhole sealing examination. The ground controller is connected to the cable digital water distributor through the cable, and two-way transmission between data and instructions is carried out through the cable, so that the data can be directly read and can be controlled in a real-time manner, and a cable communication process is stable and reliable. During a testing and allocating process, a testing and allocating instrument is not required to be butt jointed with the water distributor, water volumes are automatically adjusted directly through a ground control downhole flow control system, and blocking and clamping risks during a construction process are reduced.
