Abstract
An apparatus for determining torque on bit and bending forces in a drilling assembly. The apparatus includes a body having an inner bore defined by an inner wall and having an outer wall, the body also including first and second light bores disposed between the inner wall and the outer wall and a light emitting assembly arranged and configured to cause a light beam to enter the first and second light bores. The assembly further includes first and second light sensors disposed in or at an end of the first and second light bores, respectively, that measure a location where light that enters the first and second light bores contacts the sensors
Claims20
An apparatus for determining torque, bending, or bending force in a drilling assembly, the apparatus including:
- a body having an inner bore defined by an inner wall and having an outer wall, the body also including a passageway disposed between the inner wall and the outer wall;
- a light emitting assembly arranged and configured to cause a light beam in the passageway;
- and
- a light sensor disposed in or at an end of the passageway that measures a location where the light beam contacts the light sensor.
A method for measuring, torque, bending, or bending force in a drilling assembly, the method including:
- providing a light beam through at least a portion of a passageway in a body of the drilling assembly having an inner bore defined by an inner wall and having an outer wall, the passageway formed between the inner wall and the outer wall;
- sensing by a light sensor disposed in or at an end of the passageway a location where the light beam contacts the light sensor;
- and
- comparing the sensed location with a reference location to determine at least one of a torque, a bending and a bending force in the drilling assembly.
An apparatus for determining weight on at least a portion of a drilling assembly, the apparatus including:
- a body having an inner bore defined by an inner wall and having an outer wall, the body also including a passageway disposed between the inner wall and the outer wall;
- a light emitting assembly that includes a light source, a sensor, and a wall having an opening disposed between the light source and the sensor, the light emitting assembly arranged and configured to cause a light beam in the passageway;
- and
- a mirror disposed in the body that reflects the light beam;
- wherein a portion of the reflected light beam is directed towards the opening in the wall to contact the sensor.
