Scope

This standard specifies the terms and definitions, symbols, basic requirements for reinforcement, calculations, quality evaluation, and appendices for the reinforcement of underground gas storage well groups. This standard applies to underground gas storage wells whose working medium is compressed natural gas, and the total sulfur and hydrogen sulfide content of the natural gas should meet the technical specifications for Class I or Class II gas. This standard applies to underground gas storage wells with unqualified cementing quality, uncemented wells, and wellhead modifications. The general parameters of the gas storage wells are as follows: —— Design pressure: P≤30 MPa; —— Design temperature: -20℃～60℃; —— Vertical burial depth: ≤300 m.
