PROCEDURE FOR INCREASING PAYLOAD VOLUME OF UNDERGROUND RESERVOIR FORMED IN SOLUBLE ROCK VIA BORE WELL Russian patent published in 2010 - IPC B65G5/00 

FIELD: machine building.

SUBSTANCE: increase of payload of underground reservoir is achieved during operation cycles. Gas is pumped into an underground reservoir through annular space of casing and external flow strings of well and simultaneously fresh water is supplied via annular space of the central and external flow strings. Water is supplied into the underground reservoir till gas-brain interface is achieved at the level of a shoe of the external flow string, further gas is pumped into the underground reservoir and brine is withdrawn to surface via the central flow string. Stored gas is withdrawn via annular space of the casing and external flow strings with simultaneous supply of water through the central flow string till gas-brine interface achieves mark of upper boundary of the underground reservoir.

EFFECT: increased efficiency of raising payload volume of underground reservoirs intended for compressed gas storage.
