Automatic plunger lifting system for high-yield well

The utility model provides an automatic plunger lifting system for a high-yield well, which comprises an underground part, the underground part comprises a sleeve and an oil pipe arranged in the sleeve, and a plunger is arranged in the oil pipe; the ground part comprises a gas production tree arranged at a wellhead and a pipeline system connected with the gas production tree; the pipeline system can be communicated with the oil pipe through a pipeline and a valve to achieve production, the oil pipe is communicated with the sleeve to achieve pressure balance of the oil pipe and the sleeve, and therefore the plunger can be opened. The pressure of an oil casing can be automatically balanced through the valve, and the liquid accumulation height is reduced, so that the plunger can be smoothly started, and the problem of starting the plunger of a large-water-yield well is solved; and well opening and closing control is achieved through the second valve, and finally the purpose of automatic plunger gas lift liquid d
