High strength-to-weight-ratio slickline and multiline cables
Slickline cables and methods for preparing such cables are disclosed. A slickline cable includes a pre-manufactured polymer composite rod having a channel therein; an optical fiber disposed in the channel; a fastener securing the optical fiber in the channel, wherein the fastener is selected from the group comprising a polymer tape, a polymer layer, and a combination thereof, and an outer tube disposed outside the polymer composite rod having the optical fiber therein. A method for manufacturing a slickline cable includes preparing a polymer composite rod having at least one channel therein; placing at least one optical fiber in the at least one channel in the polymer composite rod; securing the at least one optical fiber in the at least one channel using a polymer tape, a polymer layer, or a combination of a polymer tape and a polymer layer; disposing an outer tube over the polymer composite rod.
1. A cable comprising:
a pre-manufactured polymer composite rod having a channel therein, wherein the polymer composite rod is made of a continuous or long fiber-reinforced composite;
an optical fiber disposed in the channel; and,
a fastener securing the optical fiber within the channel and enclosing the channel, wherein the fastener is formed from a material selected from the group comprising a polymer tape, a polymer layer, and a combination thereof.
2. The cable of claim 1 , further comprising an outer tube disposed outside the polymer composite rod having the optical fiber therein.
3. The cable of claim 1 , further comprising an inner tube enclosing the optical fiber.
4. The cable of claim 3 , wherein the inner tube is a metallic tube.
5. The cable of claim 4 , wherein the inner tube is a polymer tube.
6. The cable of claim 5 , wherein the polymer tube is assembled from a plurality of pieces.
7. The cable of claim 1 , wherein the polymer composite rod comprises a plurality of pieces and the channel therein is formed by assembling the plurality of pieces.
8. The cable of claim 1 , further comprising an insulating layer disposed between the outer tube and the polymer composite rod.
9. The cable of claim 2 , wherein the outer tube is a metallic tube.
10. The cable of claim 1 , further comprising at least one electrical conductor.
11. The cable of claim 10 , wherein the at least one electrical conductor is selected from an insulated conductor and a stacked dielectric conductor.
12. The cable of claim 10 , wherein the at least one electrical conductor is disposed in the channel together with the optical fiber.
13. The cable of claim 9 , wherein the at least one electrical conductor is embedded in the polymer composite rod.
14. The cable of claim 10 , further comprising a shield surrounding the at least one electrical conductor.
15. The cable of claim 14 , wherein the shield is a copper shield.
16. The cable of claim 1 wherein the cable is a slickline cable.
17. The cable of claim 1 as dispatched into a wellbore.
18. A cable comprising:
a pre-manufactured polymer composite rod having a channel therein, the polymer composite rod made of a continuous or long fiber-reinforced composite;
an optical fiber disposed in the channel; and,
an outer tube disposed outside the polymer composite rod having the optical fiber therein.
19. The cable of claim 18 further comprising a fastener securing the optical fiber within the channel and enclosing the channel.
