Designed for lowering the shank into the well, activating its technological equipment and disconnecting the transport tool from the shank after cementing.
It is intended for cementing secret casing columns in order to prevent the impact of high hydrodynamic pressure on the productiокve reservoir when selling cement solution in the annulus space.
Designed for planting displacement and suspended plugs at the moment of completion of the cementing process (receiving a "Stop" signal) during two-stage cementing.
Designed for hermetic connection of liner sections during its running in two stages using the TOKS 18 disconnector and the installation of an intermediate suspension plug with a valve assembly.
Designed for seating the displacement plug (receiving the first "Stop" signal), separating cement and drilling mud in the process of moving along the liner from the setting tool to the landing sleeve. The landing of the suspended plug together with the displacement plug into the landing sleeve serves as a "Stop" signal.
