Safety control method for cable-controlled separate injection well

The invention provides a safety control method for a cable-controlled separate injection well, and the method comprises the steps: strengthening the information safety protection of remote control instruction transmission: guaranteeing the credibility of an instruction through the modes of white list addition, transmission encryption, multi-factor authentication and industrial firewall establishment; performing risk analysis and safety protection on the operation instruction, wherein the system analyzes the performability of the current control instruction according to the control instruction limiting condition; and supervision analysis and safety control of instruction execution: identifying the execution risk of the remote operation instruction by establishing a risk identification model and a knowledge base. According to the method, a safe water injection protection method is constructed from two aspects of information safety and behavior monitoring of instruction execution; an effective solution is provid
