Uninterrupted continuous circulation system solutions providing core technical support for oil drilling operations. Maintains downhole pressure stability and improves drilling safety.
Key benefits for drilling operations
Keep continuous circulation of downhole drilling fluid pressure to avoid excitation of positive and negative pressure at the bottom of the well caused by starting/stopping the pump.
Effectively control the ECD value of annular space, maintain stable well pressure, and prevent well wall collapse and cuttings deposition.
Improve the cleaning effect of wellbore, reduce torque and friction resistance, and improve the directional effect.
Improve mud treatment effect, maintain rheology, reduce blockage, sticking, surging and spraying conditions.
