FIELD: pumps.
SUBSTANCE: group of inventions relates to pumping equipment used to pump fluid into a well, mainly into its side hole. Device for pumping fluid into well includes control station 6, tubing string 4 with two controlled packers 1, control and measuring unit 2 and pumping unit 3 between packers 1, as well as extended control device 5 for transfer of packers 1 from transport to working position and back. Assembly 3 has a recess or channel for attachment of means 5. During pumping, said equipment is placed on string 4 and moved into the well to a position in which there is a place for pumping fluid medium between packers 1. By means of means 5 packers 1 are transferred from transport to working position. After that, fluid is supplied from the wellhead into the annular space between packers 1 by means of assembly 3 bypassing the recess or the channel and means 5 arranged in it.
EFFECT: group of inventions provides the possibility of measuring and pumping fluid medium at several sections of the well without the need to remove equipment from the well, as well as reduce the probability of failure of the used equipment.
