The invention discloses an auxiliary drainage device for a natural gas well. The auxiliary drainage device comprises a natural gas compression device and also comprises a hydraulic oil pump, a hydraulic oil tank and a drainage pump, wherein an oil inlet pipe of the hydraulic oil pump is in communication with the hydraulic oil tank, the hydraulic oil pump is driven by the natural gas compression device, the hydraulic oil pump provides power for the drainage pump, and the drainage pump liquid is used for sucking liquid for pressurizing and discharging the liquid. According to the auxiliary drainage device, the natural gas compression device is utilized as the power, the electricity does not need to be consumed, and the auxiliary drainage device has the advantages of high displacement, high working efficiency and high economical efficiency.
Description
technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to an auxiliary liquid drainage device for natural gas wells. Background technique [0002] In the exploitation of natural gas, besides natural gas, gas well products also contain a large amount of liquids, and these liquids generally include gas field water and liquid hydrocarbons. In the existing mining technology, the well site does not have the ability to process liquid, and the liquid needs to be collected and transported to the processing station for treatment. Generally, a gas-liquid separation tank is installed around the wellhead, and the gas-liquid separation tank realizes the gas-liquid separation of the gas well products. After the natural gas and liquid are pressurized, they are put into the pipeline network and collected and transported to the processing station for processing. Natural gas boosting at the well site generally uses a natural gas en...
