The Spiral Drill Collars is a mechanical term that prevents the differential pressure block of the drill during drilling. The spiral groove allows the mud to flow freely around the Drill Collar to balance the pressure to prevent the formation of blockage, thus effectively preventing the differential pressure. A phenomenon occurs.
The contact area with the wellbore wall can be reduced, thereby effectively reducing the possibility of generating differential pressure blockage. The reason why the auger is widely used is because of its own characteristics. This special auger can reduce the contact area between the well wall and the pipe body, thus avoiding the "get stuck" phenomenon of the drill string.
The weight of the auger is 4 to 6% less than the weight of the round diamond.
