The wellhead intelligent injection agent system of ACZJ gas field is a set of intelligent equipment that injects a certain surfactant that can foam when encountering water from the wellhead to the bottom of the gas well. After contacting with the liquid accumulated at the bottom of the well, it generates a large amount of low-density water foam by means of natural gas flow agitation, reaches the wellhead with the gas flow, and realizes drainage and gas production.
1.“Intelligent terminal+intelligent gas well model "mode realizes intelligent injection of gas well agents
2.Independently calculate the injection amount based on the dynamic and static parameters of the gas well, remotely adjust the intelligent terminal, and achieve the optimal drainage and gas production effect
3.The system has various alarm information such as low liquid level, overpressure, low temperature, as well as fault warning information
4.The intelligent terminal adopts an integrated design concept, with a modular structure for easy installation and maintenance
