Rotatable Liner Hanger
Description
Rotatable hydromechanical liner hanger packer is designed for running the liner without cementing. The suspension includes two units:
The suspension is installed on the last pipe of the running liner and is placed inside the previous string (178 * 11.5 / 178 * 10.4 / 178 * 9.2 mm) of casing pipes in a given depth interval when casing the well, being a device that holds and fixes the assembly of the lower completion of an oil or gas well. The suspension, after firing, does not require drilling out.
Characteristics
- Maximum torque - 15 kN
- Maximum tension - 700 kN
- Packer mechanical activation - 150-200 kN
- Maximum pressure drop between the zone uncoupled by the packer - 70 MPa
- Mechanical undocking by flap to the left
- The maximum diameter of the anchor dies opening is 166.8 mm
Advantages
- Corresponds to the V0 validation class
- Completion assembly rotation capability.
- Possibility of flushing inside liner after undocking activation
- Adjustable hydraulic suspension activation
