Equipped with hydraulic rotary table, power faucet and other rotating devices, underbalanced drilling and overhaul can be carried out.
1. The lifting and lowering equipment of the pipe string is completed by the hydraulic cylinder, and the lifting and pressing speed is fast, the operation efficiency is high, and the operation is safe.The wellhead sealing device can realize pressure operation within 21MPa of wellhead.
2. Use industrial power grid for power supply and adopt full hydraulic drive to realize automatic and intelligent control.Using the principle of energy storage, the total power is only 67kW, 70% more energy saving than conventional operating equipment with the same capacity.
3. Equipped with hydraulic rotary table, power faucet and other rotating devices, underbalanced drilling and overhaul can be carried out.
