METHOD OF SAMPLING FLUID FROM GAS-LIQUID FLOW IN PIPELINE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01N1/10 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to technology and technique of fluid sampling of gas-liquid flow in pipeline and can be used in oil and other industries, where representative sample extraction by manual or automatic method is required. Method consists in fact that sample is taken from pipeline through sampling unit. At that, in pipeline flow area is formed with predominant content of liquid phase by directing rotational movement around pipeline axis, and sampling is performed from this area by sample flow rate control by means of stop valves. Device includes unit of sampling and shutoff valves. In sampling unit pipeline section for sampling is included, in which separator with formation of sampling field in form of flow cavity and injection of liquid phase, and swirler for formation of liquid phase flow in sampling area are embedded.

EFFECT: technical result consists in improvement of representativeness of test, decreasing emission of gas into environment and higher reliability of sampling technology.
