Abstract
An expander tool (40) for expanding a tubular (20) includes sets of rollers (60, 70, 80, 90) which expand the tubular (20) and which rotate transversely to the longitudinal axis of the tubular (20). The sets of rollers (60, 70, 80, 90) may be of progressively larger cross-section and may be movable between a radially retracted and extended position (fig 17). The tubular (20) can be a well screen or a solid wall tubing.
Description
( METHOD AND APPARATUS FOR INSTALLING TUBING IN A WELLRORE
The present invention relates to improvements in methods and apparatus used to install tubing in a wellbore. More particularly the present invention relates to methods 5 and apparatus for using and installing radially expandable tubular members including production liners and screens in subterranean well locations.
Radially expandable tubular members are typically moved into the well through the existing well tubing and then expanded radially to a Jarger diameter. Radial enlargement is accomplished by forcing an expanding die axially through the length of 10 tubing. An example of this prior art procedure is described in US5366012. According to
this patent, a tapered expansion mandrel 15 connected to drill string 16 is forced through the tubular member to deform it into larger diameter. The mandrel had a largest diameter greater than the internal diameter of the tubular member. In US3191677 a pall shaped expander is used. In US3785193 a tubing expander device is disclosed which is 15 positioned in the well in a retracted condition and once in position is expanded to engage the tubing. Using expansion mandrels and dies requires large axial forces and creates large friction forces, which can cause damage to the tubular member. Rotating mandrels with off set rollers thereon have been attempted but require rotational power sources.
The present invention contemplates an improved apparatus and method of 20 expanding tubular members in wellbores that overcome the problems associated with forcing expanding dies through lengths of tubing and failures caused by the large frictional forces encountered during expansion.
According to the present invention a plurality of sets of rollers carried on a tool body are moved axially through the tubular member. The roller sets define an effective 25 cross section that is larger than the cross section of the internal diameter of the tubular member. The rollers can rotate during the expansion process by engaging and rolling along the interior wall of the tubular member. The rolling action serves to reduces friction and damage to the tubular member caused thereby.
In one embodiment, the roller sets are arranged with increasingly larger effective 30 cross sections to progressively expand the tubular member. In one embodiment the rollers are retracted when the tool is moved into the well and extended to engage and expand the tubular member.

10 The present invention will be described by reference to drawings showing one or more examples of how the invention can be made and used. In these drawings, reference numerals are used throughout the several views to indicate like or corresponding parts.
In FIGURES 1 and 2, a subterranean portion of a well 10, illustrated in section, 15 has a cemented casing 12 terminating above an open hole 14. Tubing connector 16 is illustrated at the casing end for supporting a tubing assembly 20. A suitable collar 22 on the assembly 20 is designed to mate with the connector 16. Although one system is illustrated for supporting the tubing assembly there are many other systems well known in the industry suitable for use with these invention such as tubing hangers and the 20 like. In the illustrated embodiment, the tubing assembly 20 comprises a tubular member 24 coupled at 26 to a tubular screen or perforated liner section. 28. The illustrated tubing assembly is merely illustrative of many configurations of tubular members and the terms tubing assembly when used herein are generic an not intended to be limited to any particular assembly or types of tubular members and 25 include combinations or pipe, screen, liners and the like with cylindrical, corrugated and other wall shapes.
In FIGURE 1, tubing assembly 20 is illustrated being lowered through the casing 12 into the well 10 on a drill string (not shown). In FIGURE 2 the tubing assembly is expanded to a full bore diameter using an expander tool constructed in accordance 30 with the teachings of the present invention.
In FIGURES 3 an embodiment of the expander tool 40 of the present invention is illustrated. In FIGURE 3, the tool 40 is illustrated expanding a portion of
tubing assembly 20. Tool 40 has an elongated central body 42 connected to a drill string 44 by threads or the like. A plurality of tubing expander elements are longitudinally spaced on the body 42. These expander elements include a guide head 50 and four sets of rollers 60, 70, 80, and 90. The tool 40 is designed to be forced 5 down hole (in the direction of arrow add) by the weight of the drill string 44.
Alternatively, the expander could be pulled through the tubing assembly in the uphole direction. Guide head 50 is sized to fit in the tubing assembly 20. A plurality of axially extending ribs 52 engages the internal surface of the tubing assembly and centrally 10 align the tool body 40 in the tubing. The downhole facing ends 54 of these ribs 52 are tapered to guide the head into the open end of the tubing. Since the roller sets perform the expansion steps, head 50 is preferably sized to act only as a guide with a small clearance with the internal surface of the tubing assembly. However, an interference fit is acceptable with some tubing deformation occurring before roller engagement.
15 Although one guide head is shown in front of a roller set, it is envisioned that one or more guide heads could be used behind one or more roller sets to shape the tubing cross section. In addition, it is anticipated that a large number of smaller closely spaced roller assemblies could be used shape the tubing cross section after or during expansion. 20 Each of the roller sets 60, 70, 80 and 90 are typical in construction. Each has a plurality of roller assemblies 100 mounted to pivot about axis transverse to the length of the tubing assembly 20. In the illustrated embodiment, each roller assembly comprises a shaft portion 102 and at least one endless tubing member contact surface 104. In FIGURE 6 the details of an embodiment of the roller assembly 100 are shown.
25 Roller assembly 100 has a central shaft portion 102 and two spaced endless tubing contact surfaces 104. Assembly 100 is symmetrical and designed to rotate about axis 106. Axis 106 is aligned to be transverse to the tool and in a plane perpendicular to the center line 112 of the tubing assembly 20. A lubrication fitting 108 connected to internal lubrication passageways 110 can be provided to supply lubrication to the 30 surface of shaft 102.
Contact surfaces 104 are profiled to match the expanded internal surface of tubing assembly 20. This relationship is illustrated with surface 104 conforming to a
cylindrical surface with a radius R measured from the tubing center line 112, with the value of R being selected to match the expanded tubing member internal diameter.
Altematively, the roller assembly could be made with a single contact surface with a shaft on each side.
5 As can be seen in FIGURES 2, 3 and 5 each roller set contains a plurality of roller assemblies 100 spaced circumferentially about the tool body 42 with their out most surfaces arranged in a circle with a radius R larger than the unexpanded tubing assembly. For example, the roller set 60 could have a radius R an incremental amount larger than the internal diameter of the tubing assembly to be expanded. Roller sets 10 70, 80 and 90 could each have a radius R slightly larger than the adjacent dovnhole roller set (to the left in the drawings) and would progressively expand the tubing as the tool 40 is forced through it by the string 44. The endless contact surfaces 104 roll along the interior of the tubing preventing damage caused by friction forces generated using conventional expansion mandrels.
15 In FIGURE 3, the typical mounting of one of the roller assemblies 100 of roller set 90 is shown. Shaft portion 102 engages a bearing portion 120 of a bracket 122.
Lifting tool 40 causes shaft 102 to retract out of contact with the tubing section and down ramp 124 of bracket 122. Although, in this illustrated embodiment all roller assemblies utilize the ramp mounting to allow the roller to retract when the tool is lifted 20 out of the well, it is envisioned that in some well configurations only the largest roller assembles would have the ability to retract.
In FIGURE 7, a roller set is shown expanding a section of tubing 20. As can be seen the expanded tubing 20 does not exactly conform to a circle, in that, the roller surfaces 104 contacting the interior of the tubing are spaced apart and are not a 25 continuous circle. Effective cross section refers to the cross section shape of the interior of the tubing. The effective cross section has an effective radius R. effective cross sectional area A and effective circumference C. Unexpanded cylindrical tubing's effective cross section is circular. The effective cross section of expanded tubing is not necessarily completely circular.
30 As is illustrated in FIGURES 8-10, the number of roller surfaces and their spacing has an effect on the shape of the effective cross section of the tubing 20. In addition, the tubing material, thickness and amount of expansion would change the
cross section shape. Preferably, the rollers are positioned so that their highest contact point is in a circle in the plane P-P as shown in FIGURE 11. Plane P-P is transverse to the tool length and perpendicular to the tubing axis. In FIGURE 12 another configuration is illustrated with the adjacent rollers 100 axially offset. In this 5 configuration the roller contact points do not conform to a circle.
In the tool embodiment 140 illustrated in FIGURES 13-16, the roller, assemblies can be retracted during nun in and extended for the expansion step. In FIGURE 13 tubing, assembly 20 is being expanded by tool assembly 140 as it is forced (pushed in downhole direction of arrow d by drill string 44) through the tubing from right to left in 10 the figure. When using the retractable tool assembly 140 the drill string could also be connected to the tool 140 at the guide head 150 to force or pull the tool through the tubing assembly 20 in an up hole direction.
Tool assembly 140 (like tool 40) has a body 142 with a guide head 150, and a plurality of roller sets 160, 170 (not shown), 180, and 190 camed thereon. The guide 15 head and roller sets on tool assembly 140 function in the same manner as described with regard to tool 40.
Tool 140 has cylindrical outer portion 146 defining a chamber 148 in which is mounted the means for extending and retracting the roller assemblies.
Cylindrical portion 146 is illustrated as a single piece but it is fabricated (as is well 20 known in the industry) in multiple pieces connected together by threads, pins, welding and the like. These connections are not shown for simplicity purposes.
A chamber 156 and piston 158 in portion 146 define a variable volume in fluid communication with the drill string through port 162. By varying the fluid pressure in drill string 44, piston 158 can be reciprocated axially in chamber 156. In FIGURE 13 25 pressure has been raised in chamber 156 causing piston 158 to move axially in the direction of arrow d against stop 164.
An actuating rod 172 is mounted to axially reciprocate in a second chamber 174 in portion 146. Rod 172 is connected to and is moved axially by piston 158. When fluid pressure in chamber 156 moves piston 158 against stop 164, coil spring 174 is 30 compressed against wall 176 and rod 172 is moved into the chamber 156. When pressure in chamber 156 is reduced spring 174 moves piston 158 toward the drill string 44 while moving rod 172 in the same direction. Rod 172 has a plurality of cam ..
( surfaces 178 which engage and move the roller assemblies into and out of the retracted and extended positions.
In FIGURES 13-16, the interaction between the cam surface 178 on rod 172 and roller assemblies will be described. Roller assembly 200 is mounted on a bracket 5 222 similar to the non-retractable embodiment but with the roller shaft portion supported from a surface 224 which may be without the ramp, as illustrated, or may be ramped (see ramp surface 124 in FIGURE 3). Cylindrical portion 146 has a plurality of axially extending slots 182 in its wall for receiving roller brackets 222. Brackets 222 are designed to be movable with respect to portion 146 in and out of the slots 182. A 10 flange 184 (See FIGURE 16) is larger in cross section than slot 182 and is connected to bracket 222 to restrict outward movement of the bracket 222.
In FIGURE 14 the roller assembly 200 is shown in the retracted position with the cam surface 178 is axially spaced from the flange 184. When piston 158 moves the rod 178 from the FIGURE 14 retracted position to the FIGURE 15 extended position, 15 cam surface 178 engages the flange 184 forcing the roller assembly 200 outward to the extended position. A leaf spring 186 urges the bracket 222 toward the retracted position and when the rod 172 is moved out of contact with the flange 184, the roller assembly will retract.
In FIGURE 17 another roller assembly 300 embodiment is illustrated in solid line 20 extended and in dotted lines retracted. Roller bracket 322 is pivoted from tool body 342 on shaft 344. The roller assembly rotates in the directions of arrow E about axis 344 from the retracted position shown in dotted lines to the extended position shown in solid lines. A slot 346 can be formed in body 342 to allow the bracket to pivot into the body 342. A stop similar to stop 164 can be provided to limit outward rotation. An 25 actuating rod 372 is moved axially in the direction of arrow d in body 342 by the previously described piston chamber assembly to engage the bracket with cam surface 378 to extend the bracket 322. When the rod 372 is retracted a suitable spring 348 causes the bracket to rotate to the retracted position.
In FIGURE 18 a further embodiment of a retractable roller assembly 400 is 30 illustrated in solid lines in the retracted position and in dotted lines in the extended position. In this embodiment the bracket 422 is fixed to the exterior of the body 442.
Bracket 422 has an outwardly inclined ramp surface 424 supporting roller shaft 402.
.
( As the tool body 442 is moved down holed (arrow d) contact between the roller and the tubing assembly will tend to cause the roller shaft 402 to climb the ramp 424 and move to the extended position shown in dotted lines. However, during movement of the tool into position, a releasable latch shown here in the form of a pin 444 holding the shaft 5 402 in the retracted position (solid lines) at the bottom of the ramp 424. Pin 444 is biased by compression spring 446 to move in the direction of arrow X out of the path of shaft 402. Once tool body 442 is in position in the well, the actuating rod 472 is moved axially from under pin 444 allowing spring 446 to retract the pin down out of contact with the shaft 402. With pin 444 retracted, downward movement (direction of arrow d) 10 of the tool will allow shaft 402 to climb ramp 424 to the extended position to perform the tubing assembly expanding step. Once expansion is completed Irfting up on the tool body 442 will cause the roller to move down ramp 424 to the retracted position. In addition, the actuating shaft 472 can be moved downward by a cylinder-piston assembly (not shown) until cam surface 478 engages pin 444 and returns it to the 15 locking position shown in FIGURE 18.
According to the present invention the wellbore is completed through a series of steps. First, a tubing assembly is provided comprising at least in part an expandable tubular member. The tubular assembly can be a continuous tubular member, or a liner with drainage openings and/or screen. Either before or after any required perforation 20 steps, the tubing assembly is positioned in the well where it is to be expanded. Once in the desired position, the tubing assembly is radially expanded by engaging it with an expander tool having sets of rollers positioned on the tool to progressively expand the tubing assembly as the tool is moved through the tubular assembly. In the extendable tool embodiment, the tool is moved to a position adjacent the tubular member in the 25 retracted condition and expands the tubular member while in the radially extended condition. Thereafter the tool can be retracted and moved out of the well.
The embodiments shown and described above are only exemplary. Many details are often found in the art such as: actuator pistons and cylinders, expandable tubing, expandable liners, and expandable screens and the like. Therefore, many such 30 details are neither shown nor described. It is envisioned, for example, that a conventional chemical powered setting tool or the like could operate the extendable tool. It will therefore be appreciated that the invention described above may be modified.
