FIELD: oil and gas extractive industry.
SUBSTANCE: method includes transporting hydrocarbon product along operation channel. Control of pressure changes along this channel is performed. If such change is present such debit of hydrocarbon product is set, which provides for destruction or decomposition of present natural gas hydrates and/or prevention of their forming. With this debit, to place of hydrates decomposition and/or prevention of their forming, alkali solution is fed with concentration 0.04-4.9% with "pH" greater than 10. Alkali solution is fed during time not less than time of pressure change along operation channel, as well as with flow and during time until achieving mass concentration of alkali in gas phase 10-15% of mass.
EFFECT: higher efficiency.
