[0018] Such as figure 1 As shown, the natural gas recovery device and method for assisting drainage and increasing production and discharging discharge liquid is composed of a split flow discharge device 1, a settlement high-pressure recovery vessel 2, an external force discharge assist recovery device 3 and a liquid discharge device 4. The valve I 6 of the split flow discharge device and The natural gas well blowout port 5 is connected, and the pipeline behind the valve I is divided into two, and the liquid during the natural gas well blowout is split once. Valve II 7 is installed on each pipeline after a split flow to individually control each pipeline. A nozzle sleeve 8 is connected after valve II to control the flowback liquid volume when replacing the nozzle. The outlet pipe of the nozzle sleeve is at the same time Connected with valve III 9 and valve IV 10. Valve III 9 is used to relieve pressure when replacing the oil nipple. Valve IV 10 is used to close the high-pressur...
