Problems solved by technology

However, sheathing is almost ineffective in protecting the wire from stress and vibration, especially when the sheathing is made of an organic material such as PEER
Additionally, the sheath itself can be damaged by stress and vibration

Abstract

Drill string element (1) comprising a main pipe (2) with connection ends (4, 6) and protective means for at least one wire. The protective means extends within a central bore (8) of the main pipe (2). The main pipe (2) presents a first hole (14) in one of said connection ends (4) and a second hole (15) in the other connection end (6), both holes communicating with the central bore (8). The protective means comprises a guide tube (10) arranged for housing said wire, both ends of which (10) being respectively disposed within the first hole (14) and the second hole (16). Retaining means are arranged in at least one of the first hole (14) and the second hole (16) for the respective end of the guide tube (10).; The retaining means are designed so as to prevent said respective end of the guide tube from moving relative to said one of the first hole and the second hole (16) according to at least one longitudinal direction of said hole.

Description

technical field [0001] The present invention relates to oil and gas drilling, and more particularly to drill pipe provided with equipment and tools for transmitting information along a downhole drill string. Background technique [0002] In the downhole drilling industry, drill stands are used to support downhole tools so that holes may be drilled into the earth. Several downhole tools form at least a portion of the drill string. [0003] In operation, drilling fluid is typically provided under pressure at the drill rig through the drill string. The drill string may be rotated by the drill stand in order to rotate the drill bit mounted at the lower end of the drill string. [0004] Pressurized drilling fluid flows through the bore of the drill string toward the lower end of the drill string and in turn circulates toward the surface outside the drill string to provide a scour action that brings drilled soil debris to the surface. [0005] Rotation of the drill bit may opti...
