Features
Two-Stage and Two-Speed Drilling Tools can fully utilize the technical advantages of PDC bit efficient rock breaking and further improve its mechanical drilling rate in low permeability formations.
From the principle of bit breaking rock, the two-stage two-speed drilling tool is no different from the conventional PDC bit. The main difference between the two is that the specific method of rock breaking is different. The two-stage two-speed drilling tool has two drill bits with differentdiameters. A diameter drill bit drills the eye, releases the internal stress in the rock, and then uses the smaller diameter drill bit to follow the broken rock. Because the first bit bit broke through the rockIn the middle of the process, the stress field of the bottom rock has changed, and the rock resists breaking.The crushing strength is reduced, so the rock breaking efficiency of the secondary drill bit is improved.Thereby improving the overall drilling efficiency.
- Extremely hard rock formations can be drilled with motors using diamond or PDC bits.
- High penetration rates can be achieved since rotation speeds are high.
- Will allow circulation of the borehole regardless of the horsepower or torque produced by the motor.
