FIELD: oil and gas industry.
SUBSTANCE: invention relates to carbohydrates recovery, particularly to the methods for preventing the generation of hydrate, gashydrate and hydrate hydrocarbon deposits in well, especially in permafrost rocks. The method includes revealing the potential depositing zones, installing the ultrasonic emitters in the flow pipes and /or in the annular space sequentially by depth of the revealed potential depositing zones, evaluation of the current quantities of the wellhead pressure and flow rate, and periodical acoustic effect at the potential depositing zones with frequency 15-100 kHz and intensity 0.2-5 W/cm2 as far as the maximum permissible deviation of the wellhead pressure and flow rate are recorded.
EFFECT: method provides increased efficiency of carbohydrates recovery and power inputs reduction.
