    摘要: A method for defining a permissible borehole curvature includes determining curvature characteristics of at least one of a borehole and a downhole assembly in the borehole and calculating an envelope of permissible borehole curvatures from a predetermined location in the borehole based on the curvature characteristics, a direction of the borehole at the predetermined location in the borehole, and a turning angle of the borehole relative to the direction of the borehole at the predetermined location.

    摘要: A system, method and apparatus for using a tool in a borehole is disclosed. The tool is disposed in the borehole. The tool includes a member rotatable substantially independently of the tool. The member is slidably coupled to a wall of the borehole. The tool is conveyed through the borehole to produce a rotation of the member as a result of the slidable coupling between the member and the wall of the borehole. A parameter of axial motion is determined from an angle of rotation of the member.

    摘要: A method of determining when tool string parameters should be altered to avoid undesirable effects that would likely occur if the tool string were employed to drill a borehole includes, modeling portions or an entirety of the tool string in the borehole under steady state loading conditions, identifying deflections of the tool string with the modeling when buckling would occur for specific tool string parameters, and calculating whether whirl exhibiting similar deflections of the tool string to those identified during buckling would be undesirable.
