深12公里的井孔地球上人类钻掘的最深的井孔有多深呢?最深的现在已经超过11.5公里,接近12公里。地点是在苏联西北部的科拉半岛摩尔曼斯克市以西。井孔深度的最终目标为15公里,但它也不过是地球半径的二百五十分之一。在能够飞向月球的时代,还不能“直接”对地球内部进行调查,这是出人意料的。上述的井孔是为探索未来资源的线索、试验新的钻探方法、调查地球科学方面令人感兴趣的问题,经过了很好的组织才开始钻掘的。
How deep is the deepest hole drilled by human beings on Earth? The deepest now exceeds 11.5 km, nearly 12 km. The location is west of Murmansk, Kola Peninsula, in the northwest Soviet Union. The ultimate goal of wellbore depth is 15 km, but it is only one-hundredth of the Earth’s radius. It is unexpected that in an era when it can fly to the moon, it is not yet possible to “directly” investigate the interior of the earth. The wellbore described above is a clue for exploring future resources, testing new drilling methods, investigating interesting issues in geosciences, and getting well organized to begin drilling.
