摘要： A method for making a downhole electrical transmission system, having the steps of providing an electrically conductive assembly disposed within a first downhole tool string component, the assembly having a first end and being anchored to the first tool string component at a first predetermined distance from a primary shoulder of the first end of the component; stretching the assembly by pulling on a second end of the assembly with a stretching tool such that the second end of the assembly is held; enlarging the diameter of the second end of the assembly to a diameter larger than an original diameter of the assembly by flaring the second end of the assembly with a flaring tool; and anchoring the second end of the assembly to the first tool string component at a second predetermined distance from a primary shoulder of the second end of the component.

摘要： In one aspect of the invention, a swivel for use in a drilling operation comprises a body with a central bore adapted for threaded connection to a tool string component. At least one electrically conductive medium is rotationally supported within the bore and adapted to rotate with respect to an electrically conductive receiver that is rotationally fixed to and disposed within the body. The electrically conductive medium and the receiver are in electrical communication through an electrically conductive arm that is rotationally fixed to the electrically conductive medium and at least partially disposed within an electrically conductive fluid disposed within a reservoir. The reservoir comprises a rigid shape that is partially filled by the conductive fluid. A least one rotary seal is disposed intermediate the reservoir and the electrically conductive medium. The rigid shape of the reservoir is adapted to prevent the conductive fluid from accumulating around the rotary seal.
