METHOD OF CREATING UNDERGROUND STORAGE IN SOLUBLE ROCKS Russian patent published in 2005 - IPC

Abstract RU 2256596 C1

FIELD: construction of underground reservoirs in rock salt.

SUBSTANCE: according to proposed method, hydrodynamic coupling is formed between casing tube strings to force gaseous nonsolvent from one well into the other. Solvent is delivered along suspended strings of tubes of first well, and brine is taken out along suspended strings of tubes of second well until gas pressure is built on head of first well required for setting gas -brine interface to new stage of rock dissolution, and maintaining of preset thickness of insulating layer of gaseous nonsolvent in top of dissolution stage in process of formation of first underground reservoir of ground is carried out at corresponding pressure rise on head of second well obtained by control of delivery of solvent and taking out of brine.

EFFECT: reduced consumption of gas at building underground reservoirs.
