Horizontal directional drilling system with drill string tripping monitoring function
A drill rig and method of operation in which a control algorithm evaluates a drill string joint disengagement routine. During the joint disengagement routine, an operational profile of a torque applied to a drill pipe on the bore is monitored during energization of the trip drive mechanism. Rotation at the rotary drive is also monitored during the joint disengagement routine, and then the joint disengagement routine is characterized as normal or abnormal based on an operational profile of the monitored torque and a monitored rotational position change at the rotary drive. A trip process for removing the on-hole rod from the drill string is interrupted and/or a message is provided to a display to inform an operator of an abnormal trip.
一种钻机和操作方法，其中，控制算法评估钻柱接头脱开例程。在所述接头脱开例程中，在所述脱扣驱动机构的激励期间，监测施加到所述孔上钻杆的扭矩的操作曲线。在所述接头脱开例程期间，还监测所述旋转驱动器处的旋转，然后基于监测到的扭矩的操作曲线和所述旋转驱动器处的监测到的旋转位置改变，将所述接头脱开例程表征为正常或异常。中断用于从所述钻柱移除所述孔上杆的脱扣过程和/或向显示器提供消息从而通知操作者异常脱扣。
