A NEW METHOD FOR COMPACTION CORRECTION
-
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。Abstract: According to the similarity and the monotonic characteristics of the compaction curves between the compacted and the decompacted states,the paleo-porosity-depth function φ'(Z) and the paleo-density-depth function ρ'(Z) was supposed.By using the principle which formation grain volume and mass have been keeping constant,the compaction correction equations has been established. Further,the decompacted thickness S and the average paleo-density ρs can be calculated and the grain density of the compacted and decompacted states can be kept constant.
