Abstract
Aspects of the disclosure relate to methods of forming and using hybrid wirelines, and associated apparatus thereof. The method is configured to form a hybrid wireline cable that comprises a core having a conductive strand and an insulation layer disposed around the conductive strand. A first plurality of solid wires are disposed around the core to form an inner armor layer. A combination of a first plurality of stranded wires and a second plurality of solid wires are disposed around the inner armor layer to form an outer armor layer. A jacket is disposed around the inner armor layer and the outer armor layer.
Claims17
A method of forming a hybrid wireline cable, comprising:
- providing a core, the core comprising conductive strands and one or more layers of insulation disposed around the conductive strands;
- stranding a first plurality of solid wires around the core of the conductive strands and the one or more layers of insulation to form an inner armor layer;
- stranding a first plurality of stranded wires and a second plurality of solid wires around the inner armor layer in a single pass using a single preform head to form an outer armor layer;
- and
- disposing a jacket around the inner armor layer and the outer armor layer.
A method of forming a hybrid wireline cable, comprising:
- running a core through a preform head, the core comprising:
- a plurality of conductive strands;
- one or more layers of insulation disposed around the plurality of conductive strands;
- and
- a first plurality of solid wires disposed around the plurality of conductive strands and the one or more layers of insulation to form an inner armor layer;
- running a stranded wire of a first plurality of stranded wires through a first set of rollers coupled to the preform head;
- running a solid wire of a second plurality of solid wires through a second set of rollers coupled to the preform head, wherein one of the first set of rollers or the second set of rollers comprises an offset roller;
- stranding the first plurality of stranded wires and the second plurality of solid wires around the inner armor layer to form an outer armor layer;
- and
- disposing a jacket around the inner armor layer and the outer armor layer.
A method of forming a hybrid wireline cable, comprising:
- running a core through a preform head, the core comprising:
- a plurality of conductive strands;
- one or more layers of insulation disposed around the plurality of conductive strands;
- and
- a first plurality of solid wires disposed around the plurality of conductive strands and the one or more layers of insulation to form an inner armor layer;
- running a stranded wire of a first plurality of stranded wires through a first set of rollers coupled to the preform head, each of the first set of rollers comprising a groove formed therein receiving the stranded wire and having a first diameter;
- running a solid wire of a second plurality of solid wires through a second set of rollers coupled to the preform head, each of the second set of rollers comprising a groove formed therein receiving the solid wire and having a second diameter that is different than the first diameter;
- stranding the first plurality of stranded wires and the second plurality of solid wires around the inner armor layer to form an outer armor layer;
- and
- disposing a jacket around the inner armor layer and the outer armor layer.
