    摘要: A reaming tool for enlarging an earth bore in a subsurface formation in which a sub is connected to a lower end of a drill string and elongated cutter blades are pivotally secured to a lower end of the body which have cutter elements preferably in the form of rotatable cutter disks along their leading edges and a fluid delivery hose leads into fluid passages in each of the cutter blades to supply fluid under pressure to a series of fluid discharge nozzles associated with the cutter elements.

    摘要: A drilling apparatus for earth boring operations is of the type having cutter blades mounted on a support body at the lower end of a drill string and includes a novel arrangement of fluid bore sections for delivering fluid under pressure into fluid discharge passages in each of the blades and a bifurcated pivotal mounting portion on the body which enables the bore sections to supply fluid to the cutter blades through a ball joint on the pivotal axis. Modified forms of invention are specifically designed for cutter blades which are intended to perform reaming operations but include the fluid delivery system as well as an extended delivery system for delivering fluid under pressure to other tools in the drill string.

    摘要: A method and apparatus for driving at least one explosive driven projectile into an open hole or well bore of a subterranean formation for the purpose of stimulating productive formation. The apparatus is capable of pivoting within the open hole or well bore for desired firing at an angle and is also capable of deep penetration into a subterranean formation. The apparatus may also be conveyed by a tubing in horizontal drilling applications.
