METHOD FOR PRODUCTION OF GASSED BED FLUID Russian patent published in 2010 - IPC F04B47/00 F04F1/08 

FIELD: mining.

SUBSTANCE: method is realised in all stages, by means of continuous fluid lift, by mutually replaceable pneumatic double-chamber displacement pumps connected by pipelines of produced fluid, vacuum, compressed air, spent and accompanying gases, power supply cable and equipped with injection and suction channels and through channels of vacuum, spent gas, compressed gas and through wire of electric circuit, with level sensors in each working chamber, three-stroke valve, electric double-sided pneumatic distributor and control unit in each stage. As liquid is sucked into one of working chambers - lower stage, three-stroke valve of which is installed when assembled into "vacuum" position, the other chamber of the same stage is simultaneously filled with compressed gas. By signals from level sensor, control unit generates a command to switch double-sided pneumatic distributor. Afterwards compressed gas is supplied into filled chamber of lower stage. Fluid is displaced into one of working chambers of upper stage, three-stroke valve of which is installed when assembled into position "spent gas", atmospheric air and/or spent gas from which is displaced along pipeline of spent and accompanying gases through compressor into compressed gas reservoir. As fluid fills one of working chambers of upper and lower stages, by signals from level sensors of upper and lower stages, their control units generate command to switch double-sided pneumatic distributors.

EFFECT: invention makes it possible to produce gassed fluid with mechanical admixtures from depths and wells with low debit, also due to continuous lift of fluid by mutually replaceable pneumatic double-chamber displacement pumps.
