Abstract

FIELD: gas and oil producing industry. SUBSTANCE: removal of natural gas with acid components from tubing-to-casing annulus is effected by successive injection of spacer fluid and dried atmospheric air. Tubing-to-casing annulus is sealed at the moment of appearance of air in gradients in natural gas outgoing from well through tubing. In this case, determined ingredient is used in form of air oxygen and its pressure is determined by means of indigocarmino. EFFECT: simplified and low-in price method due to use of nontoxic and easily available raw material for producing protective medium. 3 cl
