Abstract:
A downhole vibratory tool for placement in drillstrings is disclosed. The downhole vibratory tool creates vibration in the drillstring while drilling. A rotary drive rotates in response to fluid flow through it, rotating a rotor having a lower end engaging an upper end of a mandrel. The mandrel is held in a main body such that it is rotationally locked with respect to the main body, but can move longitudinally within a restricted range. The lower end of the rotor and the upper end of the mandrel have interfacing surfaces. Rotation of the rotor and interaction of the interfacing surfaces creates a back-and-forth movement of the mandrel with respect to the rest of the tool, creating the desired vibratory motion.

Claim (Index 1):
An apparatus for creating vibrations downhole in a drillstring, comprising:\n an elongated main body having a longitudinal bore; a mandrel disposed in said longitudinal bore of said main body, said mandrel and said main body connected by a spline connection with said main body which permits limited longitudinal movement between said main body and said mandrel but which has said mandrel rotationally locked to said housing, said mandrel comprising a longitudinal bore, an uphole end of said mandrel comprising an upward facing interfacing surface; and a rotor rotatably disposed in said longitudinal bore of said main body, having a downward facing interfacing surface in contact with said interfacing surface of said mandrel, said rotor comprising a longitudinal bore, said rotor longitudinally fixed within said main body, wherein rotation of said rotor results in rotation of said interfacing surface of said rotor on said interfacing surface of said mandrel, the shapes of said interfacing surfaces resulting in back-and-forth longitudinal movement of said mandrel with respect to said main body.
