FIELD: oil and gas industry.
SUBSTANCE: method includes use of de-emulsifying compound and pour point depressant (PPD). According to invention at bottom hole temperature up to 80°C both reagents are supplied together into pressure-actuated operating agent - gas. When bottom hole temperature exceeds 80°C, PPD is supplied to pressure-actuated operating agent and de-emulsifying compound is supplied into the product at wellhead. Note that water-soluble de-emulsifying compound is used for watered product of 40%, and for watered product of more than 60% there used is an oil-soluble de-emulsifying compound. Any of the said reagent types can be used in interval 40-60%.
EFFECT: increase of gaslift well operation efficiency via reduction of water-oil emulsion viscosity, obtaining non-hardening stream in well as well as in submerged pipeline due to high temperature use at bottom-hole and rational use of reagents depending upon the temperature at bottom-hole.
