Drill collar – Drilling Equipment – Readyzone

Drill collar Drill collars are used to provide weight on bit and to keep drill pipe in tension. Drill pipe has a comparatively low stiffness, which makes it susceptible to bucking when under compression. Repeated bucking will eventually lead to drill pipe failure. Since elastic members can only buckle in compression, fatigue failure of drill pipe can be eliminated by…
