| Abstract: | The intelligent well control system is the machine-electro- fluid integration system using the computer to monitor and control real-time to pressure of the well mouth.The system adopted the computer electro- fluid proportional closed-loop control.The mathematical model of the system was established through the research.Putting to use the method of the PID and the expert control ,The computer autocontrol realized to the throttle well control system combining with the knowledge related to petroleum gas well control.Moving the throttle valve to the fluid the valve core displacement and the valve pressure drop carries on the quite accurate control.The maximum control pressure of the design was 105MPa.The error of the pressure control was less than 0.5MPa.Through the Talimu field test of this system it got consummation.the test indicated the system work steady,the pressure control precision was high. |
