【 摘 要 】

In order to realize the intelligentization of downhole natural gas intelligent gas production technology, a set of downhole intelligent throttles suitable for remote control was designed. This article describes the mechanical structure design and remote-control mechanism of smart throttle. Using ANSYS finite element analysis software, the mechanical structure of underground intelligent throttle is analyzed and the fluid field of key parts of throttle is analyzed. According to the finite element analysis results, the mechanical design of the throttle satisfies the requirements and can provide equipment support for the implementation of downhole natural gas intelligent gas recovery technology. Finally, through the simulated well test, the feasibility of the throttle design was verified.
