- Equipment line
- Auxiliary equipment
are designed for the duty of oil and gas well for the purpose of:
- quick-connect and hermetic connection of casing string with high-pressure line of cementing units or drilling pumps;
- preliminary fixation and release cement displacement plug and wiper sectional cementing plugs and control elements ( plugs "BOMB");
- control of the flow of buffer fluid, drilling and tamponage mud in relation to the displacement plug and wiper sectional cementing plugs .
Design advantages
- plug start control;
- fast and unhindered release of plugs;
- equalization of hydrostatic pressure under and above the plugs;
- quick-connect thread with cementing head and casing.
