Cabled digital separate layer water injection ground control apparatus

The invention provides a cabled digital separate layer water injection ground control apparatus. The cabled digital separate layer water injection ground control apparatus includes a power supply device as well as a codec, a main controller, a memory and a downhole intelligent water distribution device which are electrically connected with the power supply device respectively; the downhole intelligent water distribution device is used for acquiring flow rate data and transmitting the data to the codec; the codec is used for converting the flow rate data to analog signals and transmitting the analog signals to the main controller; and the main controller transmits the flow rate data to the memory and compares the flow rate data with injection allocation amount stored by the memory, and transmits an instruction to the downhole intelligent water distribution device when the flow rate data do not accord with the injection allocation amount, so that flow rate adjustment can be realized. With the cabled digital separate layer water injection ground control apparatus provided by the invention adopted, ground real-time control and monitoring can be realized; control can be carried out remotely; workload can be reduced effectively; a testing and distributing instrument is not needed to be arranged in a hole to perform downhole operation; all water injection layer section testing and distributing tasks can be completed through ground operation control; and testing and distributing efficiency and success rate can be greatly improved; and downhole operation risks can be decreased. The cabled digital separate layer water injection ground control apparatus has the advantages of convenient operation and simple performance.
