FIELD: drilling tools.
SUBSTANCE: invention relates to the field of electric submersible pumps (hereinafter – ESP) used in underground wells. To implement the method of extracting an electric submersible pump (ESP), installed at the end of the coiled tubing encapsulated cable (hereinafter – TEC), from the well, the free end of the TEC, passing over the ground end of the well, is opened. The longitudinal extender of the non-hollow bond connector is inserted into the free end of the TEC tube. The TEC is crimped into the crimp grooves in the non-hollow bond connector. The TEC with the ESP attached to it is pulled by means of extraction the TEC and the non-hollow bond connector to the winch until the ESP is positioned above the wellhead at the upper end of the well.
EFFECT: increased efficiency of extracting the electric submersible pump from the well without the need to close or “kill” the well.
