Abstract

The invention discloses a gas-liquid mixed transportation system and method, and relates to the field of fluid transportation systems. the invention aims at solving the problem that gas and produced liquid need to be separately transported for natural gas which is extracted from a natural gas wellhead in the prior art. The gas-liquid mixed transportation system comprises a first separator used for carrying out gas-liquid separation on the natural gas from a gas well, a supercharging device and two buffer tank assemblies, wherein the separated gas is output from a first gas outlet, the separated liquid is output from a first liquid outlet, the supercharging device is used for supercharging the gas from the first gas outlet and transmitting the gas to a conveying pipe network, two buffer tank assembliey comprise buffer tanks, the two buffer tanks are used for alternately collecting the liquid from the first liquid outlet and transmitting the collected liquid to the conveying pipe network under the driving of the gas from the outlet of the supercharging device. According to the gas-liquid mixed transportation system and method, the gas-liquid mixed transportation system provided by the invention realizes simultaneous gas and liquid mixed transportation of the natural gas with the collection liquid collected from the natural gas wellhead.

Description

technical field [0001] The invention relates to the field of fluid delivery systems, in particular to a gas-liquid mixed delivery system and method. Background technique [0002] When natural gas is extracted from natural gas wells, the produced natural gas usually carries a large amount of production fluid from the well. The main component of these production fluids is water and contains a small amount of light oil, which has certain recycling value. Since the pressure at the wellhead is low when natural gas is extracted, it is necessary to pressurize the natural gas and transport it to the long-distance pipeline network. Natural gas containing produced liquid cannot directly enter the compressor for pressurization. [0003] In related technologies, the gas-liquid separation of natural gas with production liquid produced from the wellhead is usually carried out through a separator. The separated natural gas is pressurized by a compressor and then transported to the long-di...
