| Abstract: | Drilling-string tubular failures are very costly in terms of lost rig time, lost tubular goods and even lost wells. This paper give s the position of max bending stress when tensile and compressive load is appli ed. It also gives the drill-pipe fatigue model, allowed max wellbore buil d rate can be calculated with no fatigue damage. It tables someproposals to prevent drill-string failures in rotary, and horizontal well. |
