FIELD: mining.
SUBSTANCE: installation for formation by dilution and accumulation of gas in salt cavern (26) formed by formation by dilution includes pipe string (70) intended for flow divergence, made so that a provision is made for interconnection as to fluid medium with two or more concentric pipes (2, 2A) in one main shaft of a well with at least one side hole (44) passing from internal passage (25) with external annular passage (24) interconnected with the surface under one set of X-tree with gate valves. Devices (25A) for flow control, flow diverters (47) and/or insulating tubes (22) can be introduced to the pipe string intended for flow divergence, which provides a possibility of changing a zone of dilution in the salt cavern to control the cavern shape. Besides, the pipe string intended for flow divergence and used for formation of cavern can also be used for dehydration and accumulation of gas.
EFFECT: enlarging technological capabilities; improving effectiveness of a cavern creation and use method.
