Compared with the traditional rotary table driving drill pipe drilling, the screw drilling tool has the following advantages:
1. The input flow rate of drilling fluid is directly proportional to the output speed of the drilling tool;
2. There is a linear relationship between the output torque of the drilling tool and the pressure drop generated by the drilling fluid passing through the motor;
3. The rotary power of the drilling tool is only used to drive the drill bit, which reduces the wear of the drill pipe, simplifies the operation, improves the drilling precision and saves the drilling power;
4. The output speed of the drilling tool is low, the torque is large, and the pure drilling time is long;
5. The drilling tool adopts multi-row thrust radial ball bearing group, which is resistant to high pressure and fast in footage;
6. The drill tool adopts welded hard alloy radial bearing, which has a long service life;
7. The pressure drop of the water hole of the drill bit is as high as 7.0MPa, the hydraulic power of the drill bit is large, the drill bit is rinsed clean, and the drill bit can be prevented from bagging.
