METHOD FOR SIMULTANEOUS DEVELOPMENT OF UNDERGROUND RESERVOIRS GROUP IN SOLUBLE ROCKS Russian patent published in 2010 - IPC B65G5/00 

FIELD: construction.

SUBSTANCE: invention relates to the field of underground storages construction in deposits of rock salt and may be used in oil, gas and chemical industries to make underground gas and oil depots, transshipment stations, storages of commercial oil products, salt production through drilled wells. According to invention, extracted low-mineralised brine prior to its injection for additional saturation in construction of underground reservoirs group is previously separated into flows that differ in efficiency, sending them into appropriate constructed underground reservoirs. As concentration of low-mineralised brine gets closer to saturated condition, fresh water is supplied to constructed underground reservoir of group, having least geometric volume of excavation-capacity.

EFFECT: invention provides for improved efficiency of underground reservoirs construction group due to more rational spend of dissolvent, reduced construction time, production of conditioned brine at earlier stages of construction.
