METHOD FOR SELECTING FORMATION LIQUID WITHOUT HYDROCARBON GAS PRODUCTION TO THE ATMOSPHERE Russian patent published in 2018 - IPC E21B49/08 G01N1/10 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to gas production industry, namely to a method for sampling a liquid phase at the mouth of gas wells without releasing hydrocarbon gas into the atmosphere. In a method for extracting formation fluid without discharging a hydrocarbon gas into the atmosphere, the gas-liquid mixture of the well is passed through a means for separating liquid and impurities from the gas component for a predetermined period of time. Before a tapering device is mounted on the production line of the gas well, a portion of the flow of a gas-liquid mixture passing along the production line of the well is sampled using a high-pressure hose, after which this portion of the mixture stream is passed through a droplet separator in which the formation liquid contained in the mixture is separated and the gas component is returned to the processing line.

EFFECT: use of the proposed method shortens the time of sampling, reduces the labor costs for installing the necessary equipment and for the sampling process itself, losses of hydrocarbon raw materials are eliminated.
