Abstract
An electrical isolation connector subassembly for interconnecting adjacent tubular drill rods of a drilling system used in drilling bore holes in earth formations, the connector comprising an electrically insulative sleeve being sandwiched between two electrically isolated subassembly components, the sleeve providing an exterior gap between the edges of the spaced apart electrically isolated components, the exterior gap having a width of less than 50 cm.
Claims21
An electrical isolation connector subassembly for interconnecting adjacent tubular drill rods of a drilling system used in drilling bore holes in earth formations, said connector comprising an electrically insulative sleeve being sandwiched between two electrically isolated subassembly components, the sleeve providing an exterior gap between the edges of the spaced apart electrically isolated components, the exterior gap having a width of less than 50 cm.
An electrical isolation connector subassembly for interconnecting adjacent tubular drill rods of a drilling system used in drilling bore holes in earth formations, said connector comprising:
- a first electrically isolated component;
- a second electrically isolated component;
- a plurality of insulator sleeves;
- the first electrically isolated component being adapted on one end to connect to a first tubular drill rod;
- the second electrically isolated component being adapted on one end to connect to a second tubular drill rod;
- said plurality of insulator sleeves electrically separating said first and second electrically isolated components;
- wherein at least one of said insulator sleeves is sandwiched between the first and second electrically isolated components, providing an exterior gap between the edges of the spaced apart first and second electrically isolated components, the exterior gap having a width of less than 50 cm.
An electrical isolation connector subassembly for interconnecting adjacent tubular drill rods of a drilling system used in drilling bore holes in earth formations, said connector comprising:
- a mandrel, wherein said mandrel is adapted at one end to connect to a first tubular drill rod;
- a housing, wherein said housing is adapted at one end to connect to a second tubular drill rod;
- a conductive ring located on an external surface of said connector;
- a plurality of insulator sleeves;
- said mandrel and said housing being electrically continuous;
- said conductive ring being electrically isolated from said mandrel and said housing by said insulator sleeves;
- an electrode assembly that engages said conductive ring wherein said electrode assembly is electrically isolated from said mandrel and said housing, said electrode assembly being positioned within openings in said mandrel wherein said openings extends perpendicular to the longitudinal axis of the electrical isolation connector subassembly;
- wherein said insulator sleeves are sandwiched between the conductive ring and adjacent opposing faces of the subassembly, providing an exterior gap having a width of less than 50 cm.
