Abstract: Research on the single diameter of a downhole throttling valve that can‘t adapt to the various pressure and temperature in the downhole environment，putting forward a new downhole intelligent throttling system based on the conventional downhole throttling device and the adjustable poppet valve. The system reduces the gas pressure through changing the flow area. Via the downhole temperature and pressure monitored by the sensors, the system’s Industrial Personal Computer can process the data and send a signal to allow the motor to rotate to regulate the open rate of the poppet valve in real time. Then get the stable flow rate and outlet pressure at the outlet. Using ANSYS analysis software to simulate the downhole flow filed. The results show that the throttling structure of the downhole intelligent throttling system is workable, and the simulation forms the theoretical foundation to establish the throttling system.
