摘要： A drill steel for use in mine roof bolting operations. To eliminate or reduce the possibility of fracture in drill steels used in the roof bolting operations in mines the square or hexagonal surfaces of such drill steels or the elements such as couplings, collars, and recesses that are to be connected to drill steels are machined rather than forged or welded. Pieces are joined by press fitting for assembly purposes.

摘要： A shock absorbing tool for use in pipelines and oil wells, particularly in combination with perforation guns comprises a central mass supported on two springs between the end terminal members. The shock wave is absorbed in the free oscillation of the mass. The mass is constituted by a piston assembly. A steel rope permits the shock absorbing tool to be maneuvered within the bore hole without damage to the springs.

摘要： Wear sleeve for a drill pipe coupling (10), where a sleeve (18) is arranged in a drill pipe coupling on one of the two adjoining, coupled together drill pipes (12, 14) in a drill string, where the sleeve has an outer diameter that is larger than the outer diameter of the drill pipe coupling (10) and which comprises an inner continuous bore. The inner bore comprises a threaded section (22a) arranged for joining together with a corresponding outer threaded section (22) at the one end of the drill pipe coupling (10), whereupon the sleeve (18) is arranged to be securely fastened in the drill pipe coupling to form a wear sleeve.

摘要： A downhole tool for generating a longitudinal mechanical load. In one embodiment, a downhole hammer is disclosed which is activated by applying a load on the hammer and supplying pressurizing fluid to the hammer. The hammer includes a shuttle valve and piston that are moveable between first and further position, seal faces of the shuttle valve and piston being released when the valve and the piston are in their respective further positions, to allow fluid flow through the tool. When the seal is releasing, the piston impacts a remainder of the tool to generate mechanical load. The mechanical load is cyclical by repeated movements of the shuttle valve and piston.
