Abstract

The invention discloses an intelligent plunger type water drainage and gas collection device which comprises a tube body. A control device, a valve device and a rubber sealing sleeve are arranged in the tube body. The control device comprises a pressure sensor, a control circuit board and a battery pack which are electrically connected in sequence from top to bottom. The pressure sensor is arranged below the inner wall of a pressure led-in opening. The valve device comprises a screw motor and an on-off sealing assembly from top to bottom, wherein the screw motor is provided with a motor on-off sliding block, and an on-off sealing connector is arranged on the upper portion of the on-off sealing assembly. A gas-liquid channel penetrating through the sealing assembly up and down is formed in the sealing assembly, a first gas-liquid opening is formed between the on-off sealing connector and the screw motor, and a second gas-liquid opening is formed in the lower portion of the tube body. The rubber sealing sleeve is arranged below the first gas-liquid opening and is arranged on the outer side face of the tube body in a sleeving mode. The intelligent plunger type water drainage and gas collection device is high in degree of automation, the working state can be monitored at any time, the water drainage amount can be adjusted according to the self pressure of a downhole, the well bore structure and equipment do not need to be changed, the applied well condition range is wide, and the device can be adapted to the change of a gas well flexibly.

Description

technical field [0001] The invention relates to a drainage gas recovery device for a gas well, in particular to an intelligent plunger type drainage gas recovery device. Background technique [0002] The problem of liquid accumulation at the bottom of gas wells is a common problem in natural gas production, especially in the middle and late stages of gas well production, and the problem of liquid accumulation is particularly prominent. It is necessary to take measures to drain the liquid accumulation at the bottom of the well to ensure normal gas production. The plunger gas lift drainage gas recovery technology is a kind of mechanical method. The plunger gas lift is a special form of intermittent gas lift. A solid interface is formed between the lifted gas and the produced liquid. The plunger lifts the water. Due to the existence of the plunger, it can effectively prevent the gas from going up and the liquid from falling back, thereby reducing the loss of slippage and impro...
