Operation Method

After the drill bit and the directional joint are connected and tightened, the included Angle between the large water hole of the drill bit and the directional key of the directional joint is detected.

After the drilling tool is run, the azimuth Angle of the large water hole is calculated according to the azimuth Angle of the directional key determined by the drift indicator at a single point.

Change the large water hole of the drill bit to the desired azimuth Angle, then lock the turn and start the pump drill in;

In case of deflection, take the way of side deflection, side light pressure bit, help deflection;

Deflection 2 ~ 3 meters, light pressure slow rotation into 4 ~ 5 meters;

Repeat the above operation several times, when the deviation Angle reaches the expected requirements, reduce the weight on bit and increase the speed to smooth deviation.
