Abstract
A steering tool includes an internal tube disposed inside an external tube. The internal and external tubes are arranged for longitudinal axial movement relative to one another. A distal portion of the internal tube is fixedly joined to a distal portion of the external tube. At least one of the tubes may include, over at least some of its length, two continuous, longitudinal zones of solid material separated from each other by a longitudinal gap. At least one of the tubes may include a flexible distal portion distal to the joining zone, the flexible distal portion being more flexible than other portions of that tube.
Claims9
A steering tool comprising:
- an internal tube disposed inside an external tube, said internal and external tubes being arranged for longitudinal axial movement relative to one another, wherein a distal portion of said internal tube is fixedly joined to a distal portion of said external tube at a joining zone, and said internal tube is not fixedly joined to said external tube at any point distal to said joining zone, and at least one of said internal and external tubes is formed with transverse slots near a distal end thereof, and wherein the longitudinal axial movement causes bending of the distal ends of said tubes;
- wherein at least one of said tubes comprises, over at least some length of said at least one of said tubes, two continuous, longitudinal zones of solid material separated from each other by a longitudinal gap;
- and
- wherein at least one of said tubes comprises a flexible distal portion which is entirely distal to said joining zone, and wherein said longitudinal gap comprises a separation line that extends into said flexible distal portion.
