Abstract
A method has been invented for enhancing the installability of wellbore casi ng such as for use to line a borehole through a formation or to act as a drill string and to remain in hole, after drilling, to line the borehole created b y its use. A device supporting the installation of wellbore casing into a wellbore is crimped onto the outer surface of the casing. An interference fi t is created by plastic deformation inwardly in radial direction. The device supporting casing installation can be to facilitate (1) run in through the borehole (2), to maintain positioning relative to the borehole (3) or to accommodate wear against the wall of the borehole into which the casing is run. The devices supporting the installation of wellbore casing are attached to the casing to create a connection having structurally significant axial a nd torque load transfer capacity.
Claims (11)
1. A method for preparing wellbore casing for installation comprising:
selecting a joint of casing having an outer diameter and an outer surface and capable of receiving a device thereon by crimping and selecting a device supporting the installation of wellbore casing, the device having an outer facing surface, an inner bore sufficiently large to allow insertion therethrough of the joint of casing, and at least one tubular section on the body, the portion of the inner bore extending through the tubular section having an internal diameter capable of loosely fitting about the outer diameter of the joint of casing; positioning the device on the joint of casing such that the joint of casing extends through the inner bore; and crimping the device onto the joint of casing by applying an inward, substantially radially-directed force to a plurality of points about an outer circumference of the tubular section causing it to plastically deform inwardly and come into contact with the outer surface of the joint of casing, applying such additional inward, substantially radially directed force as required to force both the tubular section of the device and the outer surface of the casing to displace inwardly an amount at least great enough so that when the force is released, an interference fit is created between the device and the casing.
selecting a joint of casing having an outer diameter and an outer surface and capable of receiving a device thereon by crimping and selecting a device supporting the installation of wellbore casing, the device having an outer facing surface, an inner bore sufficiently large to allow insertion therethrough of the joint of casing, and at least one tubular section on the body, the portion of the inner bore extending through the tubular section having an internal diameter capable of loosely fitting about the outer diameter of the joint of casing; positioning the device on the joint of casing such that the joint of casing extends through the inner bore; and crimping the device onto the joint of casing by applying an inward, substantially radially-directed force to a plurality of points about an outer circumference of the tubular section causing it to plastically deform inwardly and come into contact with the outer surface of the joint of casing, applying such additional inward, substantially radially directed force as required to force both the tubular section of the device and the outer surface of the casing to displace inwardly an amount at least great enough so that when the force is released, an interference fit is created between the device and the casing.
2. The method of claim 1 wherein the casing is for wellbore completion.
3. The method of claim 1 wherein the casing is for use in a drill string.
4. The method of claim 1 wherein the device supporting the installation is selected from those useful for facilitating run in of the casing.
5. The method of claim 4 wherein the device supporting the installation includes a ramped leading edge and the device is installed such that the ramped leading edge is positioned facing downhole.
6. The method of claim 1 wherein the device supporting the installation is selected from those for accommodating wear against the wall of the borehole into which the casing is run.
7. The method of claim 7 wherein the device supporting installation has a bearing surface on its outer facing surface, the bearing surface being selected to withstand wear against the borehole wall to a degree greater than the casing.
8. The method of claim 8 wherein the bearing surface includes hard-facing.
9. The method of claim 1 wherein the device supporting the installation is selected from those useful for positioning the casing in a borehole in which the casing is to be run.
10. The method of claim 1 wherein the device supporting installation is a centralizer.
11. The method of claim 1 wherein the device supporting installation is a wear band tool.
