FIELD: oil and gas industry.
SUBSTANCE: invention relates to the oil and gas industry and can be used in the exploration and development of gas condensate and oil fields for sampling and investigation of the component-fractional composition and physico-chemical properties of reservoir fluid. Method for isokinetic sampling of a formation fluid in the form of a gas-liquid mixture flow in a measurement line of a multiphase flow meter consists in that for a well fluid, a mode with a maximum condensate-gas ratio is first selected, and then the flow is subjected to cavitation emulsification, after which the temperature and pressure in the sampler are adjusted, providing the conditions for thermodynamic equilibrium in the "flow meter measuring line-sampler" system.
EFFECT: technical result of the invention is improved quality of selection of representative reservoir samples of gas condensate (and oil) on the surface, without the need for fluid separation.
