Orientation measurements for rig equipment
A drilling rig system may include a drilling rig including a plurality of surface rig equipment thereon and a plurality of orientation sensors disposed on the plurality of surface rig equipment. The plurality of orientation sensors may be configured to provide relational positioning of the plurality of surface rig equipment on the drilling rig.
1. A method of rigging up a drilling rig, the method comprising:
raising a mast and a substructure of the drilling rig using at least one hydraulic cylinder;
measuring a position and/or an orientation of at least one of the mast, the substructure, and the at least one hydraulic cylinder, wherein the measuring is performed in real time, and is repeated one or more times as the mast and the substructure are raised from a rig-down position to a rig-up position;
positioning the hydraulic cylinder based on the position and/or the orientation of the mast, the substructure, and/or the at least one hydraulic cylinder; and
comparing the location and/or the orientation of the first hydraulic cylinder at a chosen time to the location and/or the orientation of the second hydraulic cylinder at the chosen time.
2. The method of claim 1 , further comprising calculating a difference between the location and/or the orientation of the first hydraulic cylinder and the location and/or the orientation of the second hydraulic cylinder and comparing the difference to a threshold difference.
3. The method of claim 2 , further comprising commanding an element of the drilling rig to perform a correctional operation if the difference is greater than the threshold difference.
4. The method of claim 3 , wherein the correctional operation comprises adjusting the orientation of one or both of the hydraulic cylinders, adjusting a speed at which one or both of the hydraulic cylinders is moving, and/or stopping motion of one or both of the hydraulic cylinders.
5. A method of monitoring a drilling rig comprising a plurality of surface rig equipment, the method comprising:
measuring an orientation and/or a position of a first of the plurality of surface rig equipment;
measuring an orientation and/or a position of a second of the plurality of surface rig equipment; and
determining a relational positioning of the plurality of surface rig equipment,
wherein the measuring is performed in real time, and is repeated one or more times during rig operations, and wherein measurements are stored.
6. The method of claim 5 , further comprising comparing the orientation and/or position of the first of the plurality of surface rig equipment and the second of the plurality of surface rig equipment at a chosen present time to the orientation and/or position of the first of the plurality of surface rig equipment and the second of the plurality of surface rig equipment at a past time and calculating a difference between the present orientations and/or positions and the past orientations and/or positions.
7. The method of claim 6 , further performing a correctional operation if the difference is greater than a threshold difference.
8. The method of claim 7 , wherein the first of the plurality of surface rig equipment and second of the plurality of surface rig equipment comprise a single element of the plurality of surface rig equipment, and further comprising calculating a difference between the orientation and/or position of the first location and the orientation and/or position of the second location.
9. The method of claim 7 , further performing a correctional operation if the difference is greater than a threshold difference.
