BACKGROUND

A drilling rig system is used in common drilling methods and systems used in drilling boreholes to produce oil or other hydrocarbons. A drilling rig system may include a surface system disposed above ground at the well site and a downhole system disposed below ground. The surface system may include a substructure, a mast, and other surface equipment.

When the drilling rig system is assembled, the mast may be raised from a substantially horizontal rig-down configuration to a substantially vertical rig-up configuration using raising cylinders. It may be desired to monitor an orientation and/or position of the raising cylinders and/or the mast during this process. If the orientation of the raising cylinders and/or the mast is not known, the mast may not be oriented vertically when it is installed, which may result in uneven distribution of stresses on the mast thereby limiting the load handling capacity of the mast and may eventually result to catastrophic failure.

During operation of the drilling rig system, surface equipment may experience movement due to the operations and/or environmental conditions. It may be desired to monitor an orientation and/or position of pieces of surface equipment during rig operations. If rig operations are performed without such measurements, operations may be continued without adjustment when the surface equipment is misaligned, leading to incorrect procedures, damage to equipment, and potentially catastrophic failure.

SUMMARY

This summary is provided to introduce a selection of concepts that are further described below in the detailed description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter.

In one aspect, the present disclosure relates to a drilling rig system which may include a drilling rig comprising 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.

In another aspect, the present disclosure relates to a method of rigging up a drilling rig which may include the following steps: 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; and 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.

In another aspect, the present disclosure relates to a method of monitoring a drilling rig comprising a plurality of surface rig equipment including the following steps: 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.

Other aspects and advantages of the claimed subject matter will be apparent from the following description and the appended claims.
