FIELD: oil and gas industry.
SUBSTANCE: invention relates to the field of gas production, namely to solid-phase chemical reagents intended for foaming and removing formation water from gas fields wells in order to maintain their stable operation. A foam-forming mixture of prolonged action for foaming and removing formation water from gas fields in order to maintain their stable operation contains surfactants - agent OS-20, which is a mixture of polyoxyethylene glycol ethers of synthetic primary higher fatty alcohols of C16-C18 fraction, and alpha -olefin sodium sulphonate and foam stabilizer - carboxymethylcellulose CMC in the following ratio of components: agent OS-20: alpha-olefin sodium sulphonate: CMC, respectively, wt.%: 74:25:1, or 73:25:2, or 71:25:4, or 69:25:6, or 67:25:8, or 65:25:10.
EFFECT: productive foaming and maximum removal of formation water from gas fields wells in order to maintain their stable operation using surfactant technology.
