FIELD: devices used to perform local heat-gas-chemical treatment of difficult-to-access communication lines of oil and gas production wells, namely autonomous hydrolytic type hydrogen generator.
SUBSTANCE: hydroactive member comprises aluminum cylindrical cup filled with active mass based on metal sodium metal, protective waterproofing layer, which is removed before member usage. The protective waterproofing layer is formed of paraffin-based composition. Insert formed of sodium nitrate and sodium hydroxide is arranged between above active mass and protective layer to provide time delay to react above active mass with aqueous solution. Surface area ratio between above active mass and the cup is preferably less or equal to 50.
EFFECT: extended functional capabilities and increased efficiency of hydroactive member.
