摘要： The present invention recites a drill bit comprising a main body having an axis about which it is rotated in use, a cutting face, a connecting means for attaching the bit to a source of rotary motion, a gauge region intermediate said cutting face and the connecting means. Additionally the gauge region comprises at least one member movable between a first position in which the gauge region is bounded by an imaginary tubular surface of constant cross-section co-axial to the axis of rotation and a second position in which a portion of the member is located radially inwards, with respect to the axis of rotation, of its position when said member is in said first position. In accordance with the present invention, the gauge region whilst said member is in said second position being bound by an imaginary three dimensional conical sectional surface; and at least one actuator.

摘要： Torsional, axial and lateral vibrations introduced when a mud motor is used with a drilling tool to drill a borehole are calculated using a model. The model includes different computational modules for each of three distinct motor sections: power, transmission and bearing. The resulting calculated vibration effects are used to enhance the drilling tool and drilling operation.
