ABSTRACT:
A guide means is removably affixed to the derrick of a workover rig or the like for capturing and stabilizing a medial part of a pipe section as a pipe string is being made up and run into a wellbore. The guide apparatus is pivotally mounted to the derrick so that it can be extended into operative relationship respective to the pipe section, and is retracted clear of the string by remote control. The apparatus includes a yoke which is pivoted from a substantially vertical into a substantially horizontal position. The yoke is adjusted so that the apex thereof coincides with the central axis of the pipe, and as the yoke is moved from the retracted to the operation position, the pipe section is forced to move into the yoke apex, thereby properly aligning the pipe section with the pipe string and with the borehole. Adjustment means enables precise orientation of the yoke respective to the axial centerline of the pipe string.
