Rotary Drill Pipe

  • Dual

    Aug 01, 2010The distinguishing feature of the dual-rotary (DR) drill rig is a lower rotary drive, which is used to independently advance casing up to 40 inches, depending on the drill model. The lower drive transmits pulldown, pullback and rotational forces to the casing. A carbide-studded shoe, welded to the bottom casing joint, cuts through the overburden.

    Rotary Drill Rigs Many rotary rig masts have pinning capabilities that permit drilling at angles as much as 30 degrees out of the vertical. Drilling in this manner is necessary at large surface coal mines where overburden will be cast. Typically, angles range from 10 to 15 degrees on the back row and 20 to 23 degrees along the front row.

    Apr 19, 2016In this case, even though proper makeup torque was achieved, the drill pipe will still continue to torque up down hole. For example, a rig may have 70,000ft-lbs of rotary torque. But if you are running 5 -in. FH that has a little wear on the tool joints (under 7 -in. OD), then the torsional yield on that connection is only 62,900 ft-lbs.
