Abstract
Embodiments provide a method for centralizing a coiled tubing in a wellbore. The method includes the step of supplying a roller set to a roller set assembly system located at a surface. The roller set includes a first half and a second half. The roller set assembly system includes a first guide cable and a second guide cable. The method includes the step of installing the first half to the first guide cable and the second half to the second guide cable. The method includes the step of securing the first half and the second half to the coiled tubing such that the roller set is fixed to the coiled tubing. The method includes the step of injecting the coiled tubing into the wellbore.
Claims21
A method for centralizing a coiled tubing in a wellbore, the method comprising:
- supplying a roller set to a roller set assembly system located at a surface, the roller set comprising a first half and a second half, the roller set assembly system comprising a first guide cable and a second guide cable;
- installing the first half to the first guide cable and the second half to the second guide cable;
- securing the first half and the second half to the coiled tubing such that the roller set is fixed to the coiled tubing;
- and
- injecting the coiled tubing into the wellbore.
A method for centralizing a coiled tubing in a wellbore, the method comprising:
- securing a roller set to the coiled tubing via a roller set assembly system at a surface, the roller set comprising:
- a first half including a first roller and a first set of one or more magnetic components;
- and
- a second half including a second roller, a third roller, and a second set of one or more magnetic components,
- wherein the first half and the second half are magnetically secured to the coiled tubing,
- wherein the roller set assembly system comprises a first guide cable and a second guide cable such that the first half is removably secured to the first guide cable and the second half is removably secured to the second guide cable;
- and
- injecting the coiled tubing into the wellbore,
- wherein at least one of the first roller, the second roller, and the third roller is in contact with a wall of the wellbore to centralize the coiled tubing.
A roller set assembly system for centralizing a coiled tubing in a wellbore, the roller set assembly system comprising:
- a roller set, the roller set comprising:
- a first half including a first roller, a first hanger component, and a first set of one or more magnetic components;
- and
- a second half including a second roller, a third roller, a second hanger component, and a second set of one or more magnetic components;
- a first guide cable configured to releasively bring the first half to be secured to the coiled tubing;
- and
- a second guide cable configured to releasively bring the second half to be secured to the coiled tubing,
- wherein the first half is configured to be removably secured to the first guide cable via the first hanger component and the second half is configured to be removably secured to the second guide cable via the second hanger component;
- wherein the first half and the second half are configured to be magnetically secured to the coiled tubing and to be magnetically secured to each other, and
- wherein at least one of the first roller, the second roller, and the third roller is configured to be in contact with a wall of the wellbore to centralize the coiled tubing.
A roller set assembly system for centralizing a coiled tubing in a wellbore, the roller set assembly system comprising:
- a roller set, the roller set comprising:
- a first half including a first roller, a first hanger component, and a first set of one or more magnetic components;
- and
- a second half including a second roller, a third roller, a second hanger component, and a second set of one or more magnetic components;
- a first guide cable;
- and
- a second guide cable,
- wherein the first half is configured to be removably secured to the first guide cable via the first hanger component and the second half is configured to be removably secured to the second guide cable via the second hanger component;
- wherein the first half and the second half are configured to be magnetically secured to the coiled tubing,
- wherein at least one of the first roller, the second roller, and the third roller is configured to be in contact with a wall of the wellbore to centralize the coiled tubing,
- wherein the first half further includes a first arm and the second half further includes a second arm and a third arm, wherein the first roller, the second roller, and the third roller are positioned at distal ends of the first arm, the second arm, and the third arm, respectively,
- wherein a proximate end of the first arm includes a first ball joint attached to an outer circumference of the first half, wherein a proximate end of the second arm includes a second ball joint and a proximate end of the third arm includes a third ball joint, the second ball joint and the third ball joint attached to an outer circumference of the second half, and wherein the first ball joint, the second ball joint, and the third ball joint is configured to allow the first arm, the second arm, and the third arm, respectively, to move with respect to a longitudinal axis of the coiled tubing.
