Abstract:
A pipe handling system comprising at least one pipe magazine, a pipe conveyor system, and a pipe arm for handling pipes in conjunction with a drill rig for drilling a well bore. The pipe handling system operates to transfer pipe joints from each pipe magazine to a pipe arm via the pipe conveyor system. The pipe arm then moves to transfer each pipe to the drilling rig for connection to drill string. The pipe handling system also operates to remove each pipe from the drill string. The arm engages the pipe to be removed and moves to transfer the pipe to the pipe conveyor system. The pipe conveyor system then transfers the pipes to each pipe magazine. The system is alternatively comprises electronic sensors that measure the location of pipe. The entire system is also alternatively operated with software and a general-purpose computer.
