Abstract

FIELD: gas and oil producing industry. SUBSTANCE: method for protection of underground equipment of gas well from corrosion includes removal from casing-to-tubing annulus of acid components and moisture by injection in it of absorbent and desiccant. Indicator is added to solution at the final stage of injection. When indicator is detected in gas coming from well casing-to-tubing annulus is sealed at wellhead. Indicator is used in form of metal nitrates or nitrites. EFFECT: simplified process with its simultaneous efficiency rise due to more accurate determination of the moment of sealing of casing-to-tubing annulus. 3 cl, 2 tbl
