Control line exiting coupling

Claim 2

Means for providing flow communication through a first member with a contiguous second member having a passage therethrough comprising: an enlarged bore through said first member; a flexible tubular connector for insertion into the bore of the first member, said connector having an outside diameter substantially less than said enlarged bore; said connector positionable within the first member in a plurality of angular positions; connection means for connecting said connector to the second member adjacent the passage; and securement means sealing said connector within the bore of the first member; said securement means being located at a distance from said connection means to permit said connector to flex within the bore between the securement means and the connection means.

Claim 3

In means for making a connection through a tubing head to a threaded control line passage in a tubing hanger carried in the tubing head, the improvement which comprises a radial passageway through the wall of said tubing head, said passageway being substantially larger in section than said threaded passage so that the control line passage is within the bounds of the passageway even if the tubing hanger and tubing head are not aligned, a tubular conduit threadedly received within said threaded control line passage, said conduit having a diameter substantially smaller than the diameter of said passageway, whereby an annular opening is provided therein, a packing compression shoulder in said passageway, an annular nut threadedly received in said passageway radially outwardly from said tubing hanger and spaced away from said shoulder, and annular packing between said nut and said shoulder, said packing being compressible enough to seal against both said conduit and said passageway even when they are axially misaligned.

Claim 4

In means for making a connection through a tubing head to a threaded control line passage in a tubing hanger carried in the tubing head, the improvement which comprises a radial passageway through the wall of said tubing head, said passageway being substantially larger in section than said threaded passage so that the control line passage is within the bounds of the passageway even if the tubing hanger and tubing head are not aligned, a tubular conduit threadedly received within said threaded control line passage, said conduit having a diameter substantially smaller than the diameter of said passageway, whereby an annular opening is provided therein, a packing compression shoulder in said passageway, an annular nut threadedly received in said passageway radially outwardly from said tubing hanger and spaced away from said shoulder, and annular packing between said nut and said shoulder, said packing being compressible enough to seal against both said conduit and said passageway even when they are axially misaligned.

Claim 5

The means as defined in claim 2 further comprising means on said conduit other than threads in said passage for retaining said conduit in the passageway under pressure.

Claim 6

Means for providing a flow communication through a passage in a first member to a passage in a second member which passages are adjacent but may be misaligned; a conduit adapted for insertion into the passage of the first member; attachment means for attaching said conduit in flow communication with the second member adjacent the passage of the second member; and including seal means for sealing said conduit within the first member when said conduit and the passage of the first member are not coaxial comprising; annular ring members adapted for circumscribing said conduit and having an outer diameter substantially less than the inner diameter of the passage of the first member, packing disposed between said annular ring members; means for compressing said packing between said annular ring members causing said packing to extrude over the periphery of said annular ring members; and means for containing the extrusion of said packing to provide adequate sealing engagement between said packing, said conduit, and the first member.

Claim 7

Means for providing a flow communication through a passage in a first member to a passage in a second member which passages are adjacent but may be misaligned; a conduit adapted for insertion into the passage of the first member; attachment means for attaching said conduit in flow communication with the second member adjacent the passage of the second member; and including seal means for sealing said conduit within the first member when said conduit and the passage of the first member are not coaxial comprising; annular ring members adapted for circumscribing said conduit and having an outer diameter substantially less than the inner diameter of the passage of the first member, packing disposed between said annular ring members; means for compressing said packing between said annular ring members causing said packing to extrude over the periphery of said annular ring members; and means for containing the extrusion of said packing to provide adequate sealing engagement between said packing, said conduit, and the first member.

Claim 8

The means as defined in claim 4, said seal means being located at a distance from said attachment means to permit said conduit to flex between said attachment means and said securement means.

Claim 9

The means as defined in claim 4 further comprising packing on said conduit facilitating the removal of said securement means from the passage of the first member.

Claim 10

The means as defined in claim 4 wherein the compressing means includes means for reducing friction between said packing and said compressing means.

Claim 11

A first member having a cylindrical bore and radially extending passageway through its wall intersecting said bore; a second member received within said bore of the first member having a cylindrical surface coaxial with said bore; said cylindrical surface of said second member having a radius substantially equal to the radius of said bore; said second member having a radial passageway intersecting said surface; a tubular conduit sealingly engaging the passageway of said second member and extending radially therefrom through the passageway of the first member; the passageway of the first member having a diameter substantially larger than the diameter of said conduit and the wall of the passageway of the first member; and packing means around said conduit sealing between the conduit and said passageway of the first member.

Claim 12

A first member having a cylindrical bore and radially extending passageway through its wall intersecting said bore; a second member received within said bore of the first member having a cylindrical surface coaxial with said bore; said cylindrical surface of said second member having a radius substantially equal to the radius of said bore; said second member having a radial passageway intersecting said surface; a tubular conduit sealingly engaging the passageway of said second member and extending radially therefrom through the passageway of the first member; the passageway of the first member having a diameter substantially larger than the diameter of said conduit and the wall of the passageway of the first member; and packing means around said conduit sealing between the conduit and said passageway of the first member.

Claim 13

Apparatus as defined by claim 8 and including: a packing nut in the radially outward end of the passageway of the first member compressibly engaging said packing means, a washer around said conduit having an outside diameter less than the diameter of the passageway of the first member but greater than that of the bore of the nut, and a shoulder on said conduit intermediate said washer and the bore of the first member, said shoulder having a diameter greater than the inside diameter of said washer.
