FIELD: oil-and-gas industry.
SUBSTANCE: gas is preliminary prepared and fed to gas pipeline at pressure with additional intermittent effects applied to transferred gas at pipeline lengths. In preparation, gas hydrate-water pulp with gas hydrate content making up to 50% of its volume is produced. Said pulp is transferred in gas pipeline at thermodynamic conditions that rule pout decomposition of gas hydrate. Thin gas layer is made on gas pipeline inner surface. For this, gas pipeline perimetre is heated at separate lengths to heat the surface of gas hydrate-water pulp to temperature of gas hydrate decomposition.
EFFECT: power, capital costs and operating costs saving, lower drag.
