根据压实前后压实曲线的相似性及单调性，设定古孔隙度-深度、古密度-深度函数，结合压实前后地层骨架体积不变、骨架质量不变原理．建立回剥压实校正方程，从而恢复地层古厚度及地层古密度，并且保证压实前后地层骨架密度不变。
Based on the similarity and monotonicity of the compaction curve before and after compaction, the ancient porosity-depth, paleocontinental-depth function are set up, and the principle of invariable skeleton quality is not changed with the volume of strata before and after compaction. Back-pressure compaction correction equations are established to restore paleo-paleostatistics and paleo-paleo-formations, and ensure that the density of the strata remains the same before and after compaction.
