Method of manufacturing downhole tool string components |
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.
