In many sedimentary basins the salinity of the formation water increases with depth or compaction.
在许多沉积盆地中，地层水的含盐量随深度或压实作用而增高。
The migration force of oil is bigger than that of water and increases constantly during the source of compaction of water-wet sandy and argillaceous sediment.
在亲水砂质、泥质沉积物的压实过程中，油的运移阻力大于水，而且，在压实过程中油的运移阻力是不断增大的。
At the same time, the relationship of compaction curve, maximum dry densities, optimum water content and lime content are researched through the compaction tests.
