Kit TOKS 07 (2 stage)

Designed for running the filter and liner in two stages with a tight connection of the casing sections and subsequent cementing.
Submit application

Designed to equip the bottom of the liner when running into an open hole.

    Designed for:
  • Prevent reverse movement of the solution during cementation.
  • Prevention of fluid flow through the inner channel of pipes.
  • Reducing the weight of the casing when it is submerged in the drilling mud.
It is intended for centering and cementing columns that are lowered into the well in a side unsettled trunk.
Designed for centering downhole pipes in the inter-tube space.
Designed for hanging countersunk casing strings in a well lined with a casing string.
Designed for sealing the inter-pipe space with a chain to exclude the penetration of gas and aggressive liquids into the hardening grouting mixture.
Designed for lowering the shank into the well, activating its technological equipment and disconnecting the transport tool from the shank after cementing.
Designed to activate the hydraulic suspension, upper packer in the working state.
It is intended for separation of drilling and cement solutions in the drill string, as well as for receiving the signal of the first "Stop".

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 to disconnect the first liner section from the transportation string during two-stage cementing.
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 to suspend a liner in an open wellbore with a horizontal end.
Designed to disconnect the transportation string from the liner in wells with horizontal ends.
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.
