地下油气储层中砂岩孔隙度随深度呈指数减小的趋势可以看作是地层埋藏史的函数。利用这种演化趋势可以估计古地层的剥蚀量。
The expcnential decrease trend of porosity with deepness in sandstone of subsurface hydrccarbon-bearing reservoir may be regarded as a function of the burial history of the strata. The amount of denudation in palaeos-trata can be estimated by the evolutionary trend mentioned above.
