FIELD: engines and pumps.
SUBSTANCE: invention relates to submerged electrically driven oil extraction pumps. Proposed unit consists of submerged unit 1, string of pumping-compressor pipes (PCP) 4 connected by couplings of cable 3, control system 5 and power transformer 6. Point whereat unit 1 is jointed to PCP string 4 has branch pipe 7 made up of two parts, parallel to PCP string axis and shifted relative to each other, and third part smoothly jointed aforesaid two parts. Eccentric stabilisers 9 are mounted along aforesaid PCP string and on its couplings, that represent device designed to attach cable 3 to PCP string 4 to allow shifting PCP string casing string 8 all along their length.
EFFECT: higher efficiency, lower losses.
