FIELD: oil and gas production.
SUBSTANCE: well pumping unit for simultaneous separate development of two reservoirs in well consists of lifting string, of cable, of packer, of by-pass, of two pumps, lower of which is electric immersed, while upper one is encased. The packer is equipped with a unit for sealing a cable and with a split coupling; the lower pump is located in under-packer space; also, output of the lower pump is communicated with a case of the upper pump via the packer by means of inter-pump pipe string; the by-pass is located on it below the packer.
EFFECT: simplified design and raised reliability of pump unit operation.
