摘　　要：该文探讨了估算地层剥蚀厚度的一种方法———优化孔隙度法。对其原理作了简单介绍,并给出了应用实例,最后就该方法应用中应注意的问题进行了简单的讨论。A new approach is introduced for the optimum estimation of the amount of erosion using primary porosity data. The method is applied on both the mudstone and sandstone from Mingshui Formation of Changling depression in southern Songliao basin. The two estimations yield similar results of about 500 m of erosion. Considerations that should be taken into account in geological application are discussed at the end of the paper.
