The internally threaded connection 112 of the end portion 114 of the first tubular member 110 is a box connection, and the externally threaded connection 124 of the end portion 126 of the second tubular member 128 is a pin connection. In an exemplary embodiment, the internal diameter of the tubular sleeve 116 is at least approximately 0.020″ greater than the outside diameters of the first and second tubular members, 110 and 128. In this manner, during the threaded coupling of the first and second tubular members, 110 and 128, fluidic materials within the first and second tubular members may be vented from the tubular members.
As illustrated in
During the radial expansion and plastic deformation of the first and second tubular members, 110 and 128, the tubular sleeve 116 is also radially expanded and plastically deformed. As a result, the tubular sleeve 116 may be maintained in circumferential tension and the end portions, 114 and 126, of the first and second tubular members, 110 and 128, may be maintained in circumferential compression.
Sleeve 116 increases the axial compression loading of the connection between tubular members 110 and 128 before and after expansion by the expansion device 134. Sleeve 116 may be secured to tubular members 110 and 128 by a heat shrink fit.
In several alternative embodiments, the first and second tubular members, 110 and 128, are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global Technology L.L.C.
The use of the tubular sleeve 116 during (a) the coupling of the first tubular member 110 to the second tubular member 128, (b) the placement of the first and second tubular members in the structure 132, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, the tubular sleeve 116 protects the exterior surfaces of the end portions, 114 and 126, of the first and second tubular members, 110 and 128, during handling and insertion of the tubular members within the structure 132. In this manner, damage to the exterior surfaces of the end portions, 114 and 126, of the first and second tubular members, 110 and 128, is avoided that could otherwise result in stress concentrations that could cause a catastrophic failure during subsequent radial expansion operations. Furthermore, the tubular sleeve 116 provides an alignment guide that facilitates the insertion and threaded coupling of the second tubular member 128 to the first tubular member 110. In this manner, misalignment that could result in damage to the threaded connections, 112 and 124, of the first and second tubular members, 110 and 128, may be avoided. In addition, during the relative rotation of the second tubular member with respect to the first tubular member, required during the threaded coupling of the first and second tubular members, the tubular sleeve 116 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if the tubular sleeve 116 can be easily rotated, that would indicate that the first and second tubular members, 110 and 128, are not fully threadably coupled and in intimate contact with the internal flange 118 of the tubular sleeve. Furthermore, the tubular sleeve 116 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 110 and 128. In this manner, failure modes such as, for example, longitudinal cracks in the end portions, 114 and 126, of the first and second tubular members may be limited in severity or eliminated all together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 110 and 128, the tubular sleeve 116 may provide a fluid tight metal-to-metal seal between interior surface of the tubular sleeve 116 and the exterior surfaces of the end portions, 114 and 126, of the first and second tubular members. In this manner, fluidic materials are prevented from passing through the threaded connections, 112 and 124, of the first and second tubular members, 110 and 128, into the annulus between the first and second tubular members and the structure 132. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 110 and 128, the tubular sleeve 116 may be maintained in circumferential tension and the end portions, 114 and 126, of the first and second tubular members, 110 and 128, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve.

The first and second tubular members, 1310 and 1332, and the tubular sleeve 1318 may be positioned within another structure such as, for example, a cased or uncased wellbore, and radially expanded and plastically deformed, for example, by displacing and/or rotating a conventional expansion device within and/or through the interiors of the first and second tubular members. The tapered portions, 1322 and 1324, of the tubular sleeve 1318 facilitate the insertion and movement of the first and second tubular members within and through the structure, and the movement of the expansion device through the interiors of the first and second tubular members, 1310 and 1332, may be from top to bottom or from bottom to top.
During the radial expansion and plastic deformation of the first and second tubular members, 1310 and 1332, the tubular sleeve 1318 is also radially expanded and plastically deformed. As a result, the tubular sleeve 1318 may be maintained in circumferential tension and the end portions, 1316 and 1330, of the first and second tubular members, 1310 and 1332, may be maintained in circumferential compression.
Sleeve 1316 increases the axial compression loading of the connection between tubular members 1310 and 1332 before and after expansion by the expansion device. The sleeve 1318 may be secured to tubular members 1310 and 1332, for example, by a heat shrink fit.
During the radial expansion and plastic deformation of the first and second tubular members, 1310 and 1332, the grooves 1314 and/or 1334 and/or the openings 1326 provide stress concentrations that in turn apply added stress forces to the mating threads of the threaded connections, 1312 and 1328. As a result, during and after the radial expansion and plastic deformation of the first and second tubular members, 1310 and 1332, the mating threads of the threaded connections, 1312 and 1328, are maintained in metal to metal contact thereby providing a fluid and gas tight connection. In an exemplary embodiment, the orientations of the grooves 1314 and/or 1334 and the openings 1326 are orthogonal to one another. In an exemplary embodiment, the grooves 1314 and/or 1334 are helical grooves.
In several alternative embodiments, the first and second tubular members, 1310 and 1332, are radially expanded and plastically deformed using other conventional methods for radially expanding and plastically deforming tubular members such as, for example, internal pressurization, hydroforming, and/or roller expansion devices and/or any one or combination of the conventional commercially available expansion products and services available from Baker Hughes, Weatherford International, and/or Enventure Global Technology L.L.C.
The use of the tubular sleeve 1318 during (a) the coupling of the first tubular member 1310 to the second tubular member 1332, (b) the placement of the first and second tubular members in the structure, and (c) the radial expansion and plastic deformation of the first and second tubular members provides a number of significant benefits. For example, the tubular sleeve 1318 protects the exterior surfaces of the end portions, 1316 and 1330, of the first and second tubular members, 1310 and 1332, during handling and insertion of the tubular members within the structure. In this manner, damage to the exterior surfaces of the end portions, 1316 and 1330, of the first and second tubular members, 1310 and 1332, is avoided that could otherwise result in stress concentrations that could cause a catastrophic failure during subsequent radial expansion operations. Furthermore, the tubular sleeve 1318 provides an alignment guide that facilitates the insertion and threaded coupling of the second tubular member 1332 to the first tubular member 1310. In this manner, misalignment that could result in damage to the threaded connections, 1312 and 1328, of the first and second tubular members, 1310 and 1332, may be avoided. In addition, during the relative rotation of the second tubular member with respect to the first tubular member, required during the threaded coupling of the first and second tubular members, the tubular sleeve 1316 provides an indication of to what degree the first and second tubular members are threadably coupled. For example, if the tubular sleeve 1318 can be easily rotated, that would indicate that the first and second tubular members, 1310 and 1332, are not fully threadably coupled and in intimate contact with the internal flange 1320 of the tubular sleeve. Furthermore, the tubular sleeve 1318 may prevent crack propagation during the radial expansion and plastic deformation of the first and second tubular members, 1310 and 1332. In this manner, failure modes such as, for example, longitudinal cracks in the end portions, 1316 and 1330, of the first and second tubular members may be limited in severity or eliminated all together. In addition, after completing the radial expansion and plastic deformation of the first and second tubular members, 1310 and 1332, the tubular sleeve 1318 may provide a fluid and gas tight metal-to-metal seal between interior surface of the tubular sleeve 1318 and the exterior surfaces of the end portions, 1316 and 1330, of the first and second tubular members. In this manner, fluidic materials are prevented from passing through the threaded connections, 1312 and 1330, of the first and second tubular members, 1310 and 1332, into the annulus between the first and second tubular members and the structure. Furthermore, because, following the radial expansion and plastic deformation of the first and second tubular members, 1310 and 1332, the tubular sleeve 1318 may be maintained in circumferential tension and the end portions, 1316 and 1330, of the first and second tubular members, 1310 and 1332, may be maintained in circumferential compression, axial loads and/or torque loads may be transmitted through the tubular sleeve.
In several exemplary embodiments, the first and second tubular members are radially expanded and plastically deformed using the expansion device in a conventional manner and/or using one or more of the methods and apparatus disclosed in one or more of the following: The present application is related to the following: (1) U.S. patent application Ser.
