FIELD: oil and gas industry.
SUBSTANCE: invention includes a method of artificial lifting and system for provision of artificial lifting suitable for use in reservoirs-reservoirs of heavy oil. Method of artificial lift includes pumping combination of water and gas into well for creation of artificial lift. Combination of water and gas is transported downwards in annular space between tubing string and casing pipe or in single shared tubing string provided inside or outside the production string. Proposed system comprises combined pipe. Combined pipe passes through the Christmas tree to the annular space of the well and ends on the valve provided on the hole in the pipe element. Said pipe is configured to provide a combination of gas and water at the opening in the tubular member.
EFFECT: technical result is ensuring uninterrupted operation of well, reducing weight of downhole equipment.
