Description
- This application claims the benefit of an earlier filing date from U.S. Provisional Application Ser. No. 62/781,464 filed Dec. 18, 2018, the entire disclosure of which is incorporated herein by reference.
- In the resource exploration and recovery industry, a borehole is formed in a formation to provide access to one or more resource bearing zones. The borehole may be formed by a drill connected to a drill string made up of a number of tubulars. Once formed, a tubular string formed from any number of tubulars may be guided into the borehole for the purpose of testing and extracting formation fluids. Each tubular includes a pin or externally threaded end and a box or internally threaded end. The pin end of one tubular is threaded into a box end of another tubular to make up a joint. It is desirable that the tubulars are axially aligned while being joined to ensure a proper makeup of the joint. Misalignments may lead to thread damage, poor sealing as well as other issues.
- In some cases, tubulars may include conduits, such as electrical conductors, hydraulic conductors and the like that are joined when making up a joint. Each tubular will support a connector portion. When making up a joint that includes a connector, axial alignment is desirable in order to ensure a proper connection. When connectors are arranged centrally within the tubular, proper alignment reduces stress and improves signal clarity. Therefore, the art would appreciate a system that enhances axial alignment of tubulars during a connection process.

first connector system 40 arranged centrally infirst interior 24.First connector system 40 includes aguide member 42 having aninner wall 43 that extends about afirst connector portion 44.First connector portion 44 includes acentral recess 45.First connector portion 44 may support a conductor (not shown) that delivers a control signal tofirst connector system 40. The control signal may take on various forms including electrical current, optical signals, hydraulic signals and the like. In an embodiment,first connector portion 44 may define one of a first electrical connector portion, a first hydraulic connector portion, and a first optical connector portion. - In further accordance with an exemplary embodiment,
second tubular 16 includes anouter surface 60 and aninner surface 62 that defines asecond interior 64. Second tubular 16 includes asecond terminal end 68 that devices abox end 70 having anouter edge 73. Anangled back bore 78 extends axially alongsecond interior 64. Angledback bore 78 extends at an angle that increases radially inwardly from aboutouter edge 73 axially alongsecond interior 64. Achamfer region 80 may be formed betweenouter edge 73 and angled back bore 78. Chamferregion 80 promotes an initial alignment offirst terminal end 30 relative tosecond terminal end 68. A portion of angledback bore 78 may define an internally threadedsection 82. - In an embodiment, second tubular 16 supports a
second connector system 88 arranged centrally insecond interior 64.Second connector system 88 is configured to mate with first connector system, 40 for the purpose of passing a signal through first tubular 14 into second tubular 16 or vice versa. As discussed herein, the signal may be an electrical signal, a hydraulic signal, an optical signal or the like.Second connector system 88 includes asecond connector portion 90 that supports aconnector 92 coupled to a conductor (not shown).Connector 92 is received bycentral recess 45 when first tubular 14 is joined with second tubular 16 as will be detailed herein. In an embodiment,second connector portion 90 may define one of a second electrical connector portion, a second hydraulic connector portion, and a second optical connector portion. - In still further accordance with an exemplary aspect, a guiding
sleeve 110 is coupled to firstterminal end 30.Guiding sleeve 110 includes a first or inner guidingmember 112 and a second or outer guidingmember 114. While shown as being to components, guidingsleeve 110 may be formed as a single, unitary member.Guiding sleeve 110 includes a body (not separately labeled) having afirst end portion 118, asecond end portion 120 and anintermediate portion 122 extending therebetween. Anannular recess 128 may be formed atfirst end portion 118 between inner guidingmember 112 and outer guidingmember 114.Annular recess 128 may be receptive of unthreaded portion 39 of firstterminal end 30. Amechanical fastener 130 may extend through outer guidingmember 114 intorecess 38 to secure guidingsleeve 110 to firstterminal end 30. - In yet still further accordance with an exemplary aspect, guiding
sleeve 110 includes a guidingfeature 134 atsecond end portion 120.Guiding feature 134 may take the form of anannular projection 138 that extends entirely about, or about a portion ofsecond end portion 120. In an embodiment, guidingfeature 134 may include a generally rounded cross-section 140. It should be understood that guidingfeature 134 may take on various forms and/or geometries. It should also be understood that guidingfeature 134 may constitute a geometric attribute of guidingsleeve 110. - Guiding
sleeve 110 may be formed from a material that is softer than materials employed in the formation of first tubular 14 and/orsecond tubular 16. That is, guidingsleeve 110 is formed from a material having a hardness that is less than a hardness of first tubular 14 andsecond tubular 16. For example, guidingsleeve 110 may be formed from bronze or other similar materials. The use of a softer material reduces frozen connections that might occur if guidingsleeve 110 were formed from a material having a hardness similar to that used to form, for example,second tubular 16. In an embodiment, outer guidingmember 114 may be formed from a first material and inner guidingmember 112 may be formed from a second material that may be distinct from the first material. Inner guidingmember 112 may be formed from a material that is non-electrically conductive. - In accordance with an exemplary embodiment, guiding
sleeve 110 promotes an axial alignment of first tubular 14 relative tosecond tubular 16. The axial alignment improves a connection between pin end 32 andbox end 70. Specifically, ensuring good axial alignment reduces cross-threading issues or other connection problems that may lead to faulty sealing between first andsecond tubulars sleeve 110 allows for a first selected axial misalignment between first andsecond tubulars FIG. 1 . The first selected axial alignment accommodates an initial insertion of pin end 32 intobox end 70. Guidingfeature 134 encourages at least two points of contact (not separately labeled) between guidingsleeve 110 and angled back bore 78. - As pin end 32 moves into
box end 70 the selected amount of axial misalignment is reduced as shown inFIG. 2 . For example, guidingfeature 134 may allow no more than about 8-degrees of misalignment initially. However, as firstterminal end 30 moved into secondterminal end 68, the selected amount of misalignment may be reduced to no more than about 5-degrees. Guidingfeature 134 continues to promote at least two points of contact between guidingsleeve 110 and angled back bore 78. In this manner, guidingsleeve 110 aligns externally threadedportion 34 of pin end 32 with internally threadedsection 82 ofbox end 70 to promote a proper joint make up. At the same time, guidingsleeve 110 promotes alignment offirst connector system 40 withsecond connector system 88. - As pin end 32 is threaded into
box end 70 as shown inFIG. 3 , the selected amount of misalignment is further reduced to, for example, no more than about 2-degrees due to multiple points of contact between guidingsleeve 110inner surface 62. At this pointsecond connector portion 90 extends intoguide member 42 to alignconnector 92 withcentral recess 45. Once pin end 32 comes together withbox end 70connector 92 is arranged incentral recess 45 to provide a connection between conductor 46 and the conductor as shown inFIG. 4 . It should be understood that the selected amount of axial misalignment may vary depending upon thread type, connector type and the like. - Set forth below are some embodiments of the foregoing disclosure:
