description The invention provides a simple plunger piston device of a gas well mouth and a gas well gas production method. The simple plunger piston device of the gas well mouth comprises a gas production tree first valve, a gas production tree second valve and a gas production tree third valve which are connected with the well mouth, and a solenoid valve, wherein the other end of the gas production tree first valve is connected with a fourth valve and a fifth valve; the other end of the fourth valve is connected with a well mouth blowout prevention device; a first end of the solenoid valve is connected with the gas production tree third valve and the fifth valve; a second end of the solenoid valve is connected with a flow rate meter; and the other end of the flow rate meter is connected with a stop valve. The simple plunger piston device has the advantages that: a gas well mouth solenoid valve for opening and closing a well by adopting the solenoid valve replaces a pneumatic stop valve and an intelligent control box of a conventional plunger piston gas-lifting ground device, so that a plunger piston gas-lifting well mouth device system is simplified, the purpose of opening and closing the well through the plunger gas-lifting device by adopting the solenoid valve is realized, and the purpose of simplifying the device and reducing the cost is finally achieved.
