Spiral drill collar is widely used because of its special structure. The special grooves decrease the volume of the contact with the well wall. It leads to the decrease of the sticking and turning of the drill pipe string.
The weight of Spiral drill collar will be reduced approximately 4%-6% by spiral conversion.
