Odex Eccentric Casing Drilling System

Roschen company's eccentric drilling tool, comprising rod stabilizer and eccentric drill bit, the tail of eccentric drill bit is provided with the first boss, the inner wall of the rod stabilizer is provided with the first groove matched with the first boss, and the inner wall of the rod stabilizer is provided with the first limiting groove along the circumferential direction, the outer wall of the tail is provided with annular groove, the rod stabilizer is provided with a mounting hole, and when the mounting hole is equipped with a pin rod, the pin rod can be stuck in the annular groove.

This eccentric drilling tool loads the tail of eccentric drill bit into the rod stabilizer, the pin rod is inserted into the mounting hole, the pin rod can be stuck in the annular groove, the eccentric drill bit can not be pulled out from the rod stabilizer, the eccentric drill bit is rotated, the first boss is in contact with the groove wall of the first limiting groove, during work, the rod stabilizer drives the eccentric drill bit to rotate through the first boss and the first limiting groove cooperation, and the torque is concentrated on the first boss and the first limiting groove, and the pin rod and the annular groove will not be affected by the effect of torsion, thereby the damage of this eccentric drilling tool can be reduced, and the service life is improved.

ODEX Eccentric Overburden Drilling System Technical Specifcations:

We can design special dimensions for different casing tube diameter.

Advantages

1. Applicable to weakly stable layers: The eccentric design can provide better wellbore stability and casing guidance in loose, porous, and easily collapsed formations.
2. Fast construction speed: Some processes allow direct completion of drilling and casing installation without mud construction. So that greatly shortening the construction period.
3. Reduce wellbore friction: The eccentric casing forms irregular contact in the wellbore wall, which can reduce the overall friction of the wellbore.Thereby reducing the lifting load of the equipment.

How to buy?
If you want to buy odex drill bit, you need to tell us the OD and the wall thickness of the casing you need. We also need to know the hole diameter, the Min. ID of the casing shoe, and the model of hammer.

In general, you need to choose the most suitable eccentric casing system according to the specific geological conditions, and also construction environment, economic budget and technical requirements to ensure the safe and efficient progress of the project.
