Pay attention to these operations when using a well drill rod

When using a well drilling rod, we need to take a drill torque, push tensile power, and allow the minimum curvature radius to choose a drill rod suitable for specifications.
Remember not to connect a small diameter drill rod in a large diameter.
1. During the drilling well, the track of the well drilling machine was raised, and the mast back, and the two formed a torque to break the petal of the first water well drilling rod. In the first group of the first group of poles, the most easily breaks between the compression table and the oblique keys.
2. During the drilling rod, there was no buffer during the contact between the two adjacent rods, causing the inner rod rod rookie to impact the inner bond of the outer rod, and the outer rod pipes support the drum.
3. Do not find the pressure point when pressing, use the lock rod as a rubbing pole. The inner key in the one -pole and the two -pole diagonal key is very small. Severe wear, leading to a stuck rod or a roller.
The above three points should not be careless when using a well drill drilling drilling. When using a well drilling rod, we need to take a drill torque, push tensile power, and allow the minimum curvature radius to choose a drill rod suitable for specifications. Remember not to connect a small diameter drill rod in a large diameter.
When clamping a drill rod with a tiger, do not clamp the mother's joint part of the mother to prevent the mother buckle from being deformation. Water channel holes should be cleaned before installing the drilling rod to prevent the mud system pressure from the obstruction channel of the debris.
When installing a well drilling rod, the upper fastening pre -tightening force should be controlled within 15MPa to prevent difficulties from unloading due to excessive pressure. Avoid baking joints with fire to reduce the mechanical properties of the joints, (especially the mother joints) affect the service life.
Do not pre -tight thread connection swinging, causing the well drilling rod thread to grind the tooth top to change the tip of the tooth, and the ridge of the side is generated on the side, causing the thread to damage the goods to produce adhesion. Without pre -tightness, the parent buckle step is not tight, which can cause the fatigue of the screw of the public connector to break the fatigue. Under the influence of the high -pressure liquid flow, the parent joint is pierced, resulting in a spiny phenomenon, which can easily cause the mother joint to crack....
