Abstract
A vibrator apparatus to be positioned onto a pipe string is disclosed. The apparatus is comprised of a tubular housing, a tubular stator having a radial fluid opening, and a rotating rotor shaft with a longitudinally extending fluid bore and at least one radially extending fluid passage that intermittently aligns with the stator fluid opening. A rotation generator is provided to rotate the rotor shaft in response to fluid flow. Fluid flow through the fluid bore of the rotor shaft is discharged from the radially extending fluid passage of the rotor as it rotates in response to fluid flow and is intermittently interrupted by the stator as the rotor is rotated past the radial fluid opening in the stator thereby creating pulses in the fluid column and vibrating the pipe string.
