发明名称 COUPLING FOR CONNECTING TUBULAR ELEMENTS FOR BOTTOM-HOLE ASSEMBLIES.
摘要 The coupling comprises a tubular body with two ends of the body each provided with a portion of internal threading (14) for joining to a tubular element, the tubular body further comprising a central portion separating the two ends each provided with a portion of threading (14) and having a wall thickness greater than the wall thickness of the ends of the body. More precisely, this coupling comprises an extension segment (18) that extends from one of the ends of the tubular body, after the portion of internal threading (14), said extension segment having the same outside diameter as that of the tubular body and an inside diameter greater than or equal to that of the portion of internal threading. Moreover, the extension segment (18) comprises a housing (12), provided with an opening onto an external surface of the coupling, in which an electronically responsive identification tag is housed.
