The Application Of Vibrator In TianHuan Hollow Area

Use the vibrator to excitated artificial seismic waves, is the important way of the seismic exploration. Because the ability of the vibrator, the highest frequency can only attain to80hz, and it can’t develop bandwidths, also can not overcome the absorption on hight frequency energy in near the surface, but you can control vibrator the signal frequency and the basic feature can be stimulated human control and consistency good waves; The ability of overcome the molest is better, and can design vibrator the signal frequency to avoid some interference; Also can compensate the absorption of the ground to seismic signals; these are man-made earth vibrator and explosives vibrator difficult to do, so use can control vibrator for the exploration and have reflected the energy is sufficient to S/N and resolution to meet the needs of geological data.The paper according to the north district of the rings hollow, a combination of controllable vibrator characteristics in studying the various structures at the top of the tests to determine the different vibrator surface structure of production methods vibrator control of the quality and the surface of the conditions of the relationship, and the best method of manufacture in the TianHuan hollow, and improve the S/N in area of the TianHuan hollow.
