It is designed to improve the quality of isolation of the productive reservoir when fixing a well in order to prevent inter-reservoir flows and annular manifestations of reservoir fluids during the OSC, development and operation of the well.
It is intended for activating the hydraulic suspension, as well as for landing the sales and suspension plugs at the end of the cementing process (receiving the "Stop"signal).
It is intended for landing of the sales plug (receiving the signal of the first "Stop"), separation of cement and drilling mud in the process of moving along the shank from the installation tool to the landing coupling. Landing the suspension plug together with the sales plug in the landing clutch serves as a Stop signal.
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 installation as part of the shank both in the cementing interval and outside it, to ensure reliable isolation and separation of productive layers.
