Hydraulic cylinder type water drainage-gas recovery device

Abstract

The invention discloses a hydraulic cylinder type drainage gas recovery device, which comprises a natural gas compressor (1), a gas-liquid separation tank (2), a shaft (4) arranged in a gas well (3), and a gantry (5) beam An oil cylinder (6) is fixedly installed on the top, and the piston rod of the oil cylinder (6) is provided with a gland (7) that can slide up and down along the shaft (4), and a liquid inlet is provided on the side wall of the gas-liquid separation tank (2) (9) and the liquid outlet (10), the liquid inlet (9) is connected to the upper end of the delivery pipe (8), the gas-liquid separation tank (2) is provided with a filter screen (11), the gas-liquid separation tank (2) An air outlet (12) is arranged on the top of the gas compressor (1), an exhaust pipe (13) is connected to the output end of the natural gas compressor (1), and a jacket (14) is set on the exhaust pipe (13). The invention has the beneficial effects of realizing continuous pressurized gas lift drainage and gas recovery, reducing losses caused by liquid accumulation in gas production wells and stopping production, increasing gas production of water producing gas wells, and high production efficiency.
