Abstract
Abstract A well tool (e.g. well screen) having a single connector for fluidly connecting the shunt conduits carried by adjacent joints of a well tool to thereby eliminate the need for separate, individual connectors. The single connector is slidably mounted on the central conduit of one of the joints and has a plurality of passages therethrough, each of which is adapted to receive a respective shunt conduit on one of the adjacent joints. After the central conduits of two adjacent joints are coupled together, the single connector is moved whereby the upper ends of the respective shunts on one joint enter the lower ends of the respective passages to thereby fluidly connect the respective shunt conduits. The single connector is then secured in a connected position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
216 words
A well tool comprising: at least two joints, each of said joints comprising: a central conduit; and a plurality of parallel, axially-extending shunt conduits carried by central conduit; means for connecting said central conduits of said at least two joints together whereby said plurality of shunt conduits on one of said joints will be axially aligned respectively with said plurality of shunt conduits on the other of said joints; and a single connector for fluidly connecting respectively each of said plurality of shunt conduits on said one joint to each of said plurality of shunt conduits on said other joint; said single connector comprising: a body positioned on said central conduit of said one joint, said body having a central bore adapted to receive said central conduit of said one joint when said body is positioned on said one joint; and a plurality of passages axially extending through said body, each of said passages adapted to receive a respective one of said plurality of shunt conduits on said one joint into a first end of said passage and a respective one of said plurality of shunt conduits on said other joint into the other end of said passage to thereby fluidly connect said respective aligned shunt conduits when said single connector is in a connected position.
Claim 2
Dependent Claim
216 words
A well tool comprising: at least two joints, each of said joints comprising: a central conduit; and a plurality of parallel, axially-extending shunt conduits carried by central conduit; means for connecting said central conduits of said at least two joints together whereby said plurality of shunt conduits on one of said joints will be axially aligned respectively with said plurality of shunt conduits on the other of said joints; and a single connector for fluidly connecting respectively each of said plurality of shunt conduits on said one joint to each of said plurality of shunt conduits on said other joint; said single connector comprising: a body positioned on said central conduit of said one joint, said body having a central bore adapted to receive said central conduit of said one joint when said body is positioned on said one joint; and a plurality of passages axially extending through said body, each of said passages adapted to receive a respective one of said plurality of shunt conduits on said one joint into a first end of said passage and a respective one of said plurality of shunt conduits on said other joint into the other end of said passage to thereby fluidly connect said respective aligned shunt conduits when said single connector is in a connected position.
Claim 3
Dependent Claim
14 words
The well tool of claim 1 wherein said body is comprised of resilent material.
Claim 4
Dependent Claim
34 words
The well tool of claim 2 wherein said single connector is slidably mounted on said one joint in a disconnected position before said central conduits of said at least two joints are coupled together.
Claim 5
Dependent Claim
29 words
The well tool of claim 3 wherein said single connector is moved to said connected position after said central conduits of said at least two joints are coupled together.
Claim 6
Dependent Claim
17 words
The well tool of claim 4 including: means for securing said single connector in said connected position.
Claim 7
Dependent Claim
70 words
The well tool of claim 5 wherein said means for securing said single connector comprises: a ring slidably mounted on said central conduit of said one joint above said single connector and movable into contact with the top of said single connector when said connector is in said connected position; and means to lock said ring against further slidable movement to thereby secure said single connector in said connected position.
Claim 8
Dependent Claim
17 words
The well tool of claim 6 wherein said means to lock said ring comprises: a set screw.
Claim 9
Dependent Claim
33 words
The well tool of claim 7 wherein said body is formed of two symmetrical portions which are hinged together whereby said body can be assembled onto said central conduit of said one joint.
