FIELD: oil and gas industry.
SUBSTANCE: method for isolation of a storage reservoir for cryogenic liquefied gas includes filling of isolation material into annular space formed by wall of the inner reservoir and outer vacuum shell of the reservoir, and pumping out from this space until the required residual pressure is reached. The annular space is filled by the insulation material using cyclic filling from the bunker under maximum depression in the annular space. Preliminary prepared mixture of pearlite with granulated cotton wool is used as the isolation material. The above granulated cotton wool is made of pieces of basalt or glass superfine fibres.
EFFECT: exclusion of pearlite shrinkage, improvement of gas sheet conductivity and improvement in reliability of structures wherein the claimed method is used.
