Design advantages
- running and cementing of deviated and horizontal wells;
- cementing of sections in strained state;
- availability of several schemes of flushing holes opening during cementing of the first section;
- design options allowing for rotation of the section during lowering;
- reliable packer sealing of the junction;
- availability of a check valve;
- protective casing for connection of sections;
- possibility of emergency disconnection of the upper section from the lower one by turning to the right;
- elements of technological equipment are destroyed by PDC type chisel;
- use under significant pressure and temperature fluctuations.
