近年来苏联和其他国家的地震学研究表明,深钻和超深钻地球物理测量对于强震前兆预测和长期有效预报很有希望。在理论上、仪器研制上及有套管和无套管深钻和超深钻方法上都积累了丰富经验。但是迄今对地震予报而言,钻井地球物理方法这一手段还没有获得充分应用。很明显,由于地壳上部疏松层,大气和工业噪声三者的严重妨碍,使得最灵敏的仪器也无法捕捉能证实地震孕育的微弱信号。所以地震学家当然希望尽可能在震源区附近,并且 Seismological studies in the Soviet Union and other countries in recent years show that deep-bore and ultra-deep-bore geophysical surveys are promising for predicting strong precursors and long-term effective forecasts. In theory, the instrumentation has accumulated a wealth of experience in both casing and casingless deep and ultra-deep drilling methods. However, as far as earthquakes are reported, the well drilling geophysical method has not been fully used. Obviously, the most sensitive instruments are unable to capture the faint signals that can confirm the earthquake because of the serious obstruction of the upper crust, atmosphere and industrial noise. So seismologists certainly hope as much as possible in the vicinity of the source area, and
