FIELD: oil-and-gas industry.
SUBSTANCE: telemetric system sound bottom support includes a bottom sub, an electric module protected jacket and a centraliser. At that the centraliser executed as two co-axial elements with radial connections in between. The centralisers internal element is elongated in comparison with an external one, and in the centralisers internal element top part executed a blind hole along its axis, where an elastic element installed, made of non-magnetic material. The elastic element made of titanium or non-magnetic steel, or bronze, or metal rubber, or rubber.
EFFECT: sound bottom support parts lifetime increase, assembly simplification and its reliability increase, the support spare parts and its assembling work content decrease.
