We know that crude oil produced from Wells generally contains a certain amount of water, gas and other impurities, if not treated, it will bring many safety risks to production. Therefore, in order to obtain qualified oil and natural gas, crude oil must go through several processes such as dehydration, degassing, gas-liquid separation, metering and storage and transportation. In these processes, there is a device that plays an important role, that is, the gas-liquid separator, also known as the oil and gas three-phase separator, mainly used for wellhead oil and gas water separation and accurate measurement, generally integrated equipment, mainly composed of heating, separation, metering and control units.

It is a device that separates the crude oil produced by an oil well from the associated natural gas. The oil and gas separator is generally placed between the submersible centrifugal pump and the protector to separate the free gas in the well fluid from the well fluid, the liquid is sent to the submersible centrifugal pump, and the gas is released to the tubing and casing ring space. Sometimes the separator is also used for the separation, buffering and measurement of multi-phase oil, gas, water and sediment. There are three types of shape, vertical, horizontal and spherical.

Its advantage is the integration of heating and separation; Using computer automatic detection, to provide detailed, reliable, high-precision test data, reduce labor intensity; The pry assembly greatly reduces the workload and installation space required for on-site installation, and has greater mobility to adapt to the needs of changing oilfield production conditions, simplifying the process and facilitating operation and management.
