Abstract：In order to solve the problem that the electrical cabinet of the original production and injection

system in the same well has a low intelligence level and cannot realize remote monitoring，diagnosis，restart and

maintenance through the network，an intelligent control software for production and injection in the same well was

developed based on the LabVIEW platform，and combined with the electrical control cabinet，wellhead sensors，

valves and other equipment，a set of intelligent control system was designed to realize the intelligent monitoring of

the same well production and injection system. It ensures the stable and continuous gas production of gas wells，

improves the degree of automation，and reduces the maintenance cost.

      Key words：production and injection in the same well；intelligentization；automation；serial communication
