摘要： The present invention relates to a drill string fitted with information transmission means. The hollow rods of conductive material have their inside faces covered in an insulating material. The transmission means comprise a first electrical unit having at least a first annular electrode secured to the insulating inside face of the drill string, said electrode being in electrical contact with the mud contained inside the drill string so as to establish a flow of current in the conductive mud; and a second electrical unit disposed in said borehole, close to the top end of the drill string in order at least to receive the information contained in said electrical current.

摘要： The invention relates to a hollow drilling rod for transmitting information, said rod being for placing in a borehole filled with drilling mud. The rod comprises an electrically conductive cylindrical wall (521, 522) having an inside face, an outside face, a first end provided with a male coupling sleeve (62), and a second end provided with a female coupling sleeve (60), and being characterized in that it further comprises: a layer of electrically insulating material (70) covering the inside face over its entire length; and a conductive layer (80) covering said insulating layer and electrically connected at its ends to two electrically conductive rings, said conductive layer itself being covered by a second insulating layer (86) leaving said conductive rings in contact with the drilling mud.
