可控震源车是用于勘探石油的一门新技术。给三级伺服阀输入5～80Hz变频正弦扫描信号控制振动缸的振动,其上下往复振动产生巨大的冲击力作用于平板上,平板则以一个频率相同、大小相等、方向相反的垂直冲击力作用于地面,对地面产生强大的冲击波透过地壳,当冲击波遇到地壳中不同的介质时,部分反射回地面,捅入地里的检波器接收到的反射
Vibrator cars are a new technology for oil exploration. To the three servo valve input 5 ~ 80Hz frequency sine wave scanning signal control vibration vibration of the cylinder, the upper and lower reciprocating vibration has a huge impact on the plate, the plate is a frequency of the same, the same size, the opposite direction of the vertical impact force On the ground, a powerful shock wave is generated on the ground through the earth’s crust. When the shock wave encounters different media in the earth’s crust, it is partially reflected back to the ground and the reflection received by the geophone in the ground
