Abstract

1,250,077. Boring earth and rock. TRUSTUL DE FORAJ PITESTI. 10 Feb., 1969 [9 Feb., 1968], No. 7135/69. Heading E1F. A vibratory device for insertion in a drill string to free the, string when seized in a borehole produces repeated hydraulic shocks by periodical interruption of the circulating fluid. The device comprises an outer cylindrical body 1 having a valve seat 8 supporting a valve portion d of a tubular vibrator member 2, 3 reciprocable within the cylinder 1 and having a valve 4 therein which is biassed away from its seating j by a spring 6. The lower portion h of the vibrator member fits sealingly over a hollow member 10 at the bottom of the device. In use, the device is dropped down the drill string, its fall being retarded by resilient strips 16. After the stepped portion of the member 10 comes to rest in the drill collar, drilling fluid is pumped down the string and through the central bore of the vibrator member 2, 3 to thrust the valve 4 on to the seating j, thus producing an hydraulic shock which is transmitted to the drill collar. The increased fluid pressure behind the valve 4 causes the whole vibrator member to lift and valve d to open. Drilling fluid then flows round the exterior of the vibrator member and through openings k whereupon the valve 4 opens and the vibrator member rebounding from a resiliently mounted member 12 falls back to its original position.
