发明名称 TUBULAR STABBING GUIDE
摘要 A tubular stabbing guide (10) used to assist in the location of a pin end connection of a tubular in a box end connection (14) of another tubular forming the upper end of a drill string held and supported from the drill floor (16) of a rig. The stabbing guide (10) has a mounting frame (22) for location on the drill floor (16) and funnel-forming members (32) mounted on the frame (22). In use, the funnel-forming members (32) are moved from a retracted location spaced from the box end connection (14) to an active location surrounding the box end connection (14), such that the funnel-forming members (32) form a funnel for guiding the pin end connection into the box end connection (14).
