摘要： The present invention generally relates to a method and an apparatus for connecting an add-on pipe segment to a pipe string to lengthen the pipe string using friction stir welding. The pipe string is suspended in a borehole using a spider or some other pipe suspending device, and the lower end of the pipe segment is brought into an abutting or nearly abutting relationship with the proximal end of the pipe string positioned above the pipe suspending device and above the rig floor. The friction stir welding machine is brought to well center to weld the abutment or gap between the pipe segment and the pipe string and join the pipe segment to the pipe string to lengthen the pipe string. In one aspect, the method includes friction stir welding an expandable pipe segment to an expandable pipe string to form a lengthened expandable pipe string. The pipe segment may be comprised of two or more pipe segments that have been friction stir welded or conventionally welded to form a pipe stand. After friction stir welding to lengthen the pipe string, the lengthened pipe string is lowered into the borehole and the proximal end of the lengthened pipe string is favorably positioned to abut or nearly abut a new add-on pipe segment for friction stir welding at the resulting abutment or gap. The friction stir welding process provides a highly reliable pipe joint for expansion.
摘要翻译：本发明一般涉及一种用于使用摩擦搅拌焊接将附加管段连接到管柱以延长管柱的方法和装置。管柱使用蜘蛛或其他管状悬挂装置悬挂在钻孔中，并且管段的下端与位于管悬挂装置上方的管柱的近端形成邻接或几乎邻接的关系，在钻台上方。将摩擦搅拌焊接机置于中心，焊接管段和管柱之间的邻接或间隙，并将管段连接到管柱上以延长管柱。在一个方面，该方法包括将可膨胀管段摩擦搅拌焊接到可膨胀管柱以形成延长的可膨胀管柱。管段可以由已经摩擦搅拌焊接或常规焊接以形成管架的两个或更多个管段组成。在摩擦搅拌焊接以延长管柱之后，延长的管柱下降到钻孔中，并且加长管柱的近端被有利地定位成邻接或几乎邻接用于摩擦搅拌焊接的新的附加管段，由此产生基台或间隙。摩擦搅拌焊接工艺为膨胀提供了高可靠性的管接头。
