Abstract
The present invention provides a field weldable connection. In one embodiment, the field weldable connection is a downhole connector assembly for sealingly attaching a first and a second segment of a control line. The control line has an outer housing that encapsulates a polymeric secondary housing. A communication line runs therethrough the secondary housing. The connector further comprises a weld coupling welded to the outer housing of the first and second segments of the control line. To protect the communication line from the thermal radiation and heat generated during the welding process, at least one reflective sleeve replaces a portion of the secondary housing at a location intermediate the communication line and the welds of the coupling.
Claims34
A downhole connector assembly for sealingly attaching a first segment 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, said at least one weld coupling comprising welds;
- and
- at least one reflective sleeve located between the communication line and the welds of said at least one weld coupling,
- wherein an insulating gap is located between said at least one reflective sleeve and the welds of said at least one 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 located between the outer housings and the communication lines welded to the outer housings of the first and second cables;
- and
- at least one reflective sleeve of the first and second cables replacing at least a portion of the polymeric secondary housings of the first and second cables, and located intermediate the welds of said at least one weld coupling and the communication lines,
- wherein an insulating gap is located between said at least one reflective sleeve and said at least one weld coupling.
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 protecting the communication line from thermal radiation, said means replacing a portion of the polymeric secondary housing, said means located between the communication line and said at least one weld coupling and thermally insulated from said at least one weld coupling.
