通过对松辽盆地油田地下水的深入研究
发现多数影响因素对地下水化学性质的影响随着埋深的增加发生阶段性的变化
从而导致油田水化学的垂直分带性。根据地下水矿化度和Cl

浓度变化特征
从浅到深可以划分出大气水下渗淡化带(A带)、近地表蒸发浓缩带(B带)、泥岩压实排水淡化(C

The influences of most factors on chemical characteristics of oilfield water change with the increase of burial depth
leading to the vertical zonation of oilfield water.According to the changes of groundwater salinity and Cl
concentration
five typical hydrochemical profile units could be divided from the shallow to the deep part
including meteoric water infiltration fresh zone (zone A);near surface evaporative concentration zone (zone B);fresh water from mudstone compaction (C
) and concentration zone by mudstone compaction and water-seepage (C
);clay mineral dehydration fresh zone (zone D); and deep concentration zone from seepage (zone E).
