GUIDE ASSEMBLY AND METHOD

摘要

An anchor (A) or guide assembly (GA) connects with a workstring (WS) that may include a drill string (DS). The guide assembly (GA) includes an internal tubular member (ITM) to releasably connect with the workstring (WS). A tube (CT) is within the internal tubular member (ITM). The internal tubular member (ITM) is releasably secured with an outer tubular member (OTM). The internal tubular member (ITM) is releasably secured with an anchor surface. The workstring (WS) is released from the internal tubular member (ITM) to move relative to the guide assembly (GA) to extend the tube (CT) from the internal tubular member (ITM) for performing various operations. Orienting sub (38) enables operations to be performed at various azimuths and directions from a location, and in this event the outer tubular member (OTM) includes a heel window (58) and a face window (57) and the internal tubular member (ITM) has articulations (55', 55'') to bend the internal tubular member (ITM) or tube (CT) therein laterally to direct the tube (CT) laterally of a location when the workstring (WS) is lowered.
