一、问题的提出: 随着钻探技术的不断进步以及石油和其它目的深孔钻探的普遍进行,为科研和生产提供了大量有关深层地下水化学成分和化学性质的宝贵资料。 结合区域地质构造和地层岩性特点,分析整理这些资料时,会从中发现这样一个有趣而重要的问题。这就是:埋藏在各类构造盆地中的无论是同一含水层(水平方向上)还是多个含水层(垂直方向上)中的承压水,按其化学成分和矿化度的空间分布,是存在着一定的规 I. PROBLEM PROBLEMS: The continuous advancement of drilling technology and the widespread practice of deep-hole drilling for oil and other purposes have provided a wealth of valuable information on the chemical composition and chemistry of deep groundwater for scientific research and production. Combined with the regional geological structure and stratigraphic lithology, analyzing and sorting out these data will find such an interesting and important issue. This is: The confined water buried in all kinds of structural basins, whether in the same aquifer (in the horizontal direction) or in multiple aquifers (in the vertical direction), is classified according to its chemical composition and degree of mineralization There are certain rules
