Abstract
A method and apparatus for making and breaking tubular connections at the surface of a well by utilizing a pipe joining system. The pipe joining system includes a movable support frame for supporting and integrating on a rig floor the tools associated with making and breaking the connection between two tubulars. Tools incorporated in the pipe joining system include combinations of a wrenching assembly for gripping the tubulars and applying torque to the connection, a spinner for spinning the joints of the tubulars into connection, a positioning tool for vertically and/or horizontally aligning the tubulars in the system, a cleaning and doping device for cleaning and doping the threads of the tubulars, a stabbing guide for properly aligning the tubulars before joining, a mud bucket for handling mud spillage during the breaking of the tubulars, and a control system that remotely operates the entire automated system.
