ABSTRACT:
An apparatus and seismic method for producing an shock wave in an oil well borehole, with a pumping unit arranged at the wellhead, a tubing string extending downward into the production casing of the well, a hollow cylinder assembly connected with the bottom of the tube string, and pair of plungers arranged within the cylinder assembly and connected with the pumping unit with sucker rods and a polish rod for compressing liquid contained within the cylinder assembly and discharging the compressed liquid into the production casing, thereby generating a shock wave. The cylinder assembly includes an upper cylinder, a lower cylinder below the upper cylinder, a crossover cylinder below the upper and lower cylinders, and a compression chamber cylinder containing a compression chamber arranged between the crossover cylinder and the upper cylinder. The lower cylinder is adapted to receive the lower plunger, and the upper cylinder is adapted to receive the upper plunger. The lower plunger has a larger diameter than the upper plunger, and the plunger movement effects the volume of the compression chamber by reduction, the liquid contained therein becomes compressed and is discharged on the down stroke into the well. In addition, remote seismic data is collected and processed from remote well locations.
