Claims27
A downhole connector assembly for sealingly attaching a first and a second segment of a control line having an outer housing that encapsulates a polymeric secondary housing having a communication line therein that extends therefrom, comprising:
- at least one weld coupling welded to the outer housing of the first and second segment of the control line;
- and
- at least one thermal insulator separate from the secondary housing, said at least one thermal insulator located between the communication line and the welds of the weld coupling.
A protective splice assembly, comprising:
- a first cable having an outer housing and a polymeric secondary housing having a communication line therein;
- a second cable having an outer housing and a polymeric secondary housing having a communication line therein;
- a spliced connection between the communication lines of the first and second cables;
- at least one weld coupling welded to the outer housings of the first and second cables;
- and
- wherein the first cable comprises a thermal insulator separate from the polymeric secondary housing and located intermediate said at least one weld and the communication line of the first cable.
A downhole connector assembly for sealingly attaching a first and a second segment of a control line having a polymeric secondary housing having a communication line therein, comprising:
- at least one weld coupling;
- and
- means for thermally protecting the communication line, said means comprising a thermal insulator separate from the polymeric secondary housing and located between the communication line and the weld coupling.
A method for providing a downhole control line, comprising:
- providing a first and a second segment of a control line having a polymeric secondary housing having a communication line therein;
- removing a portion of the secondary housing to create a void around the communication line;
- inserting at least one thermal insulator into the void around the communication line;
- providing a weld coupling;
- and
- inserting the first and second segments of the control line into the weld coupling and welding the segments in place.
