FIELD: soil or rocks drilling.
SUBSTANCE: group of inventions refers to the field of research, data transmission and electric power in boreholes. System comprises an electric drive downhole tool, a flexible pipe escape string, attached to a downhole tool, for accommodating a downhole tool in a hollow wellbore, a pipe-cable disposed within a coiled tubing string and operatively associated with a downhole tool. Pipe-cable is configured to supply electricity and transmit data along its length to or from the downhole tool. Downhole tool has a housing with one or more spacers that are selectively pushed outward from the housing in response to the command transmitted through the cable duct. Spacers are configured to move the slide coupling device within the hollow wellbore between open and closed positions by moving the bottom hole assembly within the wellbore.
EFFECT: increased efficiency of research and management of downhole processes.
