METHOD OF PUMPING-OVER OF GAS-LIQUID MIXTURE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2009 - IPC F04B19/06 

FIELD: oil-and-gas industry.

SUBSTANCE: invention is provided for usage in oil-producing industry for pumping-over of well product. Pumping-over method of liquid-gas mixture includes feeding of pumped-over portion of liquid-gas mixture into top part of vertically located tank, allowing constant cross-section by height and contenting working fluid. Separation of liquid-gas mixture portion for two parts, from which the first top part allows required specific density, and the second part allows specific density higher than required specific density Deposition of the second part of mixture into working fluid. Displacement of working fluid together with located in it of second part of liquid-gas mixture from tank in its bottom part under pressure of liquid-gas mixture portion. Treatment of working fluid. Pressing of liquid-gas mixture portion in tank under pressure of working fluid, returned into tank in its bottom part. Withdrawing of pressed liquid-gas mixture portion from tank. Device for pumping-over of liquid-gas mixture contains working chamber with vertically located tank of identical cross-section with working fluid, in which it is located with ability free movement upwards-downwards inside the tank mediums separator of float-type, allowing specific density, equal to required specific density of pumped-over mixture.

EFFECT: improvement of conditions of scaling and regulation of equipment productivity.
