地震勘探这一种勘探方法的命名,源自希腊词-地震。地震时地层内发生各个方向的弹性振盪或弹性波。这种弹性波可以用人工的方法在浅孔内放炮造成。弹性波传播的规律与光波和音波相同。这种波由一种岩石进入另一种岩石时会改变自己的方向(发生屈折);会因为所穿过的岩石的密度、可压缩性在硬度不同而改变速度(弹性波的速度,在
Seismic exploration This method of exploration is named after the Greek word - Earthquakes. Elastic oscillations or elastic waves in all directions occurred in the earthquakes during the earthquake. This elastic wave can be artificially fired in shallow holes. The law of elastic wave propagation is the same as that of light wave and sound wave. This wave changes its direction (inflection) as it enters one rock from another rock; it changes its speed due to the difference in hardness due to the density and compressibility of the rock being passed through
