FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to sampling of deep wells. Proposed device comprises suction-type sample intake chamber with separation piston, check valve and check valve seat, ballast chamber with pressure regulator, sample pressurisation mechanism with compressed gas chamber, pressurisation fluid chamber and pressurisation piston, control and data exchange module, sample input channel and valve. Said sample pressurisation mechanism is arranged between sample intake chamber and ballast chamber, and equipped with uncoupler with piston and holder. Note here that sample intake chamber is provided with extra moving piston with check valve.
EFFECT: simplified sample pressurisation mechanism.
