    摘要： Apparatus (14) for supporting a cable (16) in a fluid-filled pipe (10) extending through an underground borehole, comprising a body (14) for connection to an end of the cable extending along the pipe, the body being buoyant in the fluid filling the pipe, such that when the body is connected to the end of the pipe, it floats at or near the surface (15) of the fluid in the pipe. A method of supporting a cable in a fluid-filled pipe using such apparatus, comprises connecting the cable to the body, and dropping the body into the pipe so as to float on the surface of the fluid filing the pipe.

    摘要： Many wellbore service operations involve placing a line in the wellbore. The line may be used to transmit power to downhole tools, convey signals from downhole-measurement instruments, or both. A problem associated with such operations involves drag forces experienced by the line as process fluids flow through the well, particularly the interior of a tubular body such as casing. The drag forces may cause the line to fail. Magnetizing the line solves this problem. During deployment, the line will migrate and become attached to the casing. Drag forces are significantly reduced because the line is no longer surrounded by moving fluid.
