摘要： A drilling rig includes a torque track system configured to couple to a derrick and to a top drive of the drilling rig, where the torque track system is configured to resist movement of the top drive in a lateral direction with respect to the derrick and to transfer torsional loads to the derrick in an operating configuration, a first torque track segment of the torque track system, and a second torque track segment of the torque track system coupled to the first torque track segment with a joint. The joint is configured to enable the first torque track segment and the second torque track segment to pivot with respect to one another while maintaining a physical connection between the first torque track segment and the second torque track segment during manipulation of the torque track system into and out of the operating configuration.

摘要： The present disclosure is directed to systems and methods for estimating rotational velocity and/or torque of a drill bit during certain drilling operations using torque and rotational velocity measured at a top drive system of the drilling operations. In certain embodiments, a drilling control system may estimate the rotational velocity and/or the torque of the drill bit using torque and rotational velocity detected at the top drive system, in conjunction with the governing equations of the drill string, the top drive, and the bottom hole assembly (including the drill bit itself), which may be transferred into the Laplace domain. In other embodiments, the drilling control system may estimate the rotational velocity and/or the torque of the drill bit using the torque and rotational velocity detected at the top drive system, in conjunction with a finite dimensional model approximation of the drill string based on an assumed mode shape of the drill string or a finite element model of the drill string.
