Abstract
A splicing system that accommodates the splicing of tubing having internal power cable. The splice system is amenable to use in subterranean environments where sections of continuous tubing are spliced along with the splicing of internal power cable. The splice technique comprises utilization of an expandable connector that permits lineal movement of the internal segments of power cable.
Claims30
A tubing system for use in a subterranean environment, comprising:
- an upper tubing section having an upper power cable segment therein;
- a lower tubing section having a lower power cable segment therein;
- and
- an intermediate tubing section having an electrical connector that is axially expandable therein, wherein the upper and the lower tubing sections are coupled to generally opposite ends of the intermediate tubing section and the electrical connector is electrically coupled to the upper and lower power cable.
A tubing splice system, comprising:
- an intermediate tubing section coupled to a pair of adjacent tubing sections by a pair of mechanical connectors each having an outside diameter that does not substantially exceed the diameter of each adjacent tubing section;
- and
- a power cable extending through the pair of tubing sections, the power cable being spliced by an electrical connector disposed within the intermediate tubing section between the pair of mechanical connectors.
An electrical connector for connecting segments of power cable, comprising:
- an outer housing sized to fit within a segment of coiled tubing;
- a conductive receptacle disposed within the outer housing, the conductive receptacle being electrically coupled to a first power cable segment;
- and
- a conductive extension sized for slidable receipt in the conductive receptacle, the conductive extension being coupled to a second power cable segment.
A method for splicing tubing having an internal power cable for use in providing power to an electric submersible pumping system, comprising:
- coupling an intermediate tubing section between a pair of tubing sections of equal diameter to the intermediate tubing section via a pair of mechanical connectors;
- and
- splicing an internal power cable within the intermediate tubing section.
A system for splicing tubing having an internal power cable for use in providing power to an electric submersible pumping system, comprising:
- means for coupling an intermediate coiled tubing section between a pair of coiled tubing sections via a pair of mechanical connectors;
- and
- means for splicing an internal power cable within the intermediate coiled tubing section.
