摘要:
A high power opto-electrical cable with multiple power and telemetry paths and a method for manufacturing the same includes at least one cable core element and at least one high-power conductor core element incased in a polymer material jacket layer. The cable core element has at least one longitudinally extending optical fiber surrounded by a pair of longitudinally extending arcuate metallic wall sections forming a tube and a polymer material jacket layer surrounding and incasing the wall sections, wherein the optical fiber transmits data and the wall sections transmit at least one of electrical power and data.

A cable includes an electrically conductive cable core for transmitting electrical power and data, an insulative/protective layer circumferentially disposed around the core, an inner armor wire layer including a plurality of armor wires disposed around the cable core and the insulative layer, wherein at least one of the armor wires of the inner armor wire layer is bonded to the insulative layer, and an outer armor wire layer including a plurality of armor wires disposed around the inner armor wire layer. At least one of the armor wires of the outer armor wire layer can be bonded to the at least one of the armor wires of the inner armor wire layer.
摘要:
An apparatus or system comprising, or a method utilizing, a pressure-tight head assembly coupling a multi-conductor wireline cable operable for downhole operations within a borehole extending into a subterranean formation. The head assembly comprises: an upper head attachment; a lower head attachment; an upper compression seal assembly; a gripper cone; and a rope socket. The upper compression seal assembly is threaded into and/or otherwise coupled to the upper head attachment in a manner causing the gripper cone to tighten onto the cable jacket.

A wire includes a ferrous core. The ferrous core can be coated. The coatings can include nickel, molybdenum, zinc and Fe. A process of forming a wire can include placing a metal strip alongside a ferrous wire core, bending the strip around the core, and seam welding the strip to form a metal tube around the core. The process of forming a wire can include applying a metal layer to a ferrous metal rod to form a plated rod, placing a metal strip alongside the rod, bending the strip around the rod, and seam welding the strip to form a metal tube around the rod. The process of forming a wire can include coating a ferrous wire core with a layer of nickel, molybdenum or a nickel alloy that circumferentially surrounds the ferrous wire core.
