摘要
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。
According to the similtrity and the montonic characteristics of the comaction curves between the compacted and the decompacted states, the paleo-porosity-depth function (Z) and the paleo-density-depth function (Z) was supnd. By using the principle which formation grain volume and mass have been keeping consant,the compaction corrction equations has been established. Further, the decomacted thickness S and the average paleo-density s can be calculated and the grain density of the compacted and decomacted states can be kept constant.
