Description
- This application claims priority to non-provisional application Ser. No. 11/717,449, filed Mar. 13, 2007, which claims priority to provisional application 60/783,884 filed Mar. 20, 2006, the entire contents of each which are incorporated herein by reference.
- In the hydrocarbon exploration and recovery arts it is increasingly common to see monitoring and/or control type devices in the downhole environment that require signal bearing connections to remote controllers, including surface controllers. Because downhole systems are generally built in pieces this necessitates the connection of signal conveying conduits while in the downhole environment, which often will be a dirty and wet environment. Dirty, wet environments in which connectors are intended to both mate and function, makes for challenges with respect to the connectors themselves. Careful consideration is necessary to prepare proper connections. In addition, since connections are often made several miles distant from the well operator, consideration with respect to alignment and mechanical forces is necessary. Because of these issues the types of connections that can be made in the downhole environment have been relatively limited and generally are costly to produce.
- A downhole optic fiber wet-connect system including first and second matable portions of a tool body. First and second matable portions of a connector body further including a first magnet associated with one of the first and second matable portions of the connector body, and a second magnet associated with the other of the first and second matable portions of the connector body. The first and second magnets being oriented to attract one another. A first opening in one of the first and second matable portions of the tool body. A second opening in the other of the first and second matable portions of the tool body. At least one of the first and second openings in the first and second matable portions of the tool body being configured and dimensioned to laterally loosely receive one of the first and second matable portions of the connector body therein.
- A method for wet-connecting an optic fiber in a downhole environment including supporting one of a first and second portion of a connector body with a flex-support within an opening of a first portion of a tool body, the opening loosely receiving the connector body portion. Moving the other of the first and second portions of the connector, the other portion being located within a second portion of the tool body, into mating contact with the one of the first and second portions. Buckling the flex-support to decouple a mechanical load on the connector from the mating of the first and second portions of the tool body.

FIG. 1 is a perspective illustration of male and female portions of a connector body in an exploded relationship to one another; -
FIG. 2 illustrates in partial phantom the components ofFIG. 1 in a mated condition; -
FIG. 3 illustrates an alternate embodiment of a connector body wherein a clean fluid and containment member are illustrated; -
FIG. 4 is a schematic illustration of a portion of the tool body having the male portion of the connector body disposed therein and supported by a flex-support; -
FIG. 5 is a schematic illustration of a portion of the tool body having the female portion of the connector body disposed therein and supported by a flex-support; and -
FIG. 6 is a schematic illustration of the illustrations ofFIGS. 4 and 5 in a connected configuration. - Referring to
FIG. 1 , aconnector body 10 is illustrated having amale portion 12 and afemale portion 14. The portions are illustrated as cylindrical bodies but it will be understood that any geometrical shape is acceptable.Male portion 12 includes aprojection 16 that is receivable in relatively tight communication with arecess 18 infemale portion 14. A depth dimension ofrecess 18 is to be selected to simply ensure a reliable optical interface.Male projection 16 includes anoptical fiber face 20 which is intended to rest in close proximity, or in one embodiment in physical contact, to a femaleoptical fiber face 22 when thefirst portion 12 andsecond portion 14, are mated, thus a length of the male projection is to be appropriate to the depth dimension of therecess 18. Each of the lengths noted are measured from ashoulder 27 and ashoulder 29 ofmale portion 12 andfemale portion 14, respectively. - To aid in alignment of
male portion 12 andfemale portion 14 during mating of theconnector body 10,projection 16 includes abeveled edge 24 which may communicate with afrustoconical surface 26 infemale portion 14 to urge at least one of themale portion 12 and thefemale portion 14 into a better aligned position with respect to the other of themale portion 12 andfemale portion 14. It is also quite possible that bothmale portion 12 andfemale portion 14 will move relative to one another upon intersection ofbeveled edge 24 andfrustoconical surface 26. The phrase “may communicate” has been used here because it is also serendipitously possible that the male and female portions will align without contact between thebeveled edge 24 andsurface 26. Upon initial alignment of themale portion 12 and female 14 due to interaction betweenbeveled edge 24 andfrustoconical surface 26 as well as themale projection 16 and the female recess 18, a magnetic interaction is utilized to assist the mating process. Amagnet 28 on themale portion 12 and amagnet 30 on thefemale portion 14, are arranged so as to be attracted to one another. Themagnets male portion 12 and thefemale portion 14 of theconnector body 10 into fully mated engagement.Magnets Further magnets magnets connector body 10, the attractive force tends to holdportions connector body 10 together. - Still referring to
FIG. 1 , anoptical fiber segment 32 is illustrated extending from themale portion 12 and anoptical fiber segment 34 is illustrated extending from thefemale portion 14. Disposed atoptical fiber segments support 36 and flex-support 38, respectively. The flex-supports have for their purpose to support, respectively, themale portion 12 andfemale portion 14 ofconnector body 10 in a desired location within a tool body discussed hereinunder with reference toFIGS. 4-6 . It is noted that drawingFIGS. 4-6 depict the configuration disclosed herein within otherwise commercially available tools from Baker Oil Tools under product number H488-75 and H444-75, referring to a packer and reconnect anchor respectively. The components of these tools are not germane to the invention and are therefore not described in detail). The flex-support 38, for example, will have sufficient stiffness to holdfemale portion 14 of the connector body in a relatively stationary position providing no significant additional load is placed uponfemale portion 14 ofconnector body 10. The stiffness ofsupport 38 is selected to be insufficient to maintain a position offemale portion 14 when any significant load is placed thereon. In such event, flex-support 38 will buckle in one or more of a number of ways calculated to be such that theoptic fiber 34 therein is not damaged. Such calculated ways include bending in a helical pattern, in a gentle bow pattern, and other patterns which facilitate smooth large radius bends in the optic fiber rather than sharp bends thereof, which tend to degrade performance of the fiber. Further with respect to stiffness, it is intended that the stiffness of flex-support portion 12 andportion 14 to effectively yield their positions to external forces. Flex-supports 36 and 38 therefore secure the triple purpose of supporting the connector portion in place, flexing to allow alignment thereof and decoupling mechanical load in the connector. It is to be understood that either or both of the flex-supports illustrated may have these properties. Greater flexibility is achievable with flex-supports having these properties when supporting both themale portion 12 and thefemale portion 14 as is illustrated inFIGS. 4-6 . With both portions flexibly supported a greater degree of movement of the connector body is possible. The flex-support decoupling concept is important because theconnector body portions connector body portions openings tool body portions FIGS. 4-6 ). This allows for theconnector body portion tool body portion 44 if the receiving opening 40 were closely tolerant to the connector body. Multiple degrees of freedom are provided by the flex-support 38 and/or 36. InFIG. 6 it can be visually appreciated that there is a bow in the flex-supports support 36, flex-support 38, or both 36 and 38 may be utilized in any particular application. Providing that at least one portion of theconnector body 10 is supported by a flex-support, and not otherwise hard mounted in the tool body, the benefits of the arrangement set forth herein are achieved. - In an alternate embodiment of the
connector body 110, and referring toFIG. 3 , aclean fluid 50 is contained withinrecess 18 by acontainment member 52. The containment member is openable upon approach ofmale projection 16 or indeed by contact offace 20 ofmale projection 16 with themember 52, in the event thatmember 52 is a rupturable membrane. This embodiment allows theconnector body 10 to flush itself of any contaminants that otherwise might nestle themselves betweenface 20 and face 22 thereby impeding optical transmission fromfiber section 32 tofiber section 34 or vice versa. Upon opening ofmember 52,clean fluid 50, which may be, for example, a hydraulic fluid or index matching gel or other optically compatible fluid, is forced to move between the interstitial relatively annular space defined betweenmale projection 16 andrecess 18. Pressure for the expulsion of such fluid is generated by the advance ofprojection 16 into therecess 18. The clean fluid displaces contaminants that might otherwise impede optical transmission. In other respects this embodiment is similar to the foregoing embodiment.
