摘要
本文提出了一种多种信息综合计算剥蚀厚度的新方法,它基于地震地层学原理,综合地质和钻井资料,利用几何作图法的散点运算,逐点分析,用钻井资料提供的小范围剥蚀情况划分区域,综合计算剥蚀厚度。
Erosional thickness is an important parameter in both in basin simulation and in the computation of source rock volume.There are many ways,nowa- days,for computing erosional thickness,such as depositional compensation, vitrinite reflectance,drilling data,geometric mapping and seismic stratigraphy and so on.All these methods have both advantages and disadvantages in each of them.A multi-information method for computing erosional thickness is pre- sented in this paper,which integrates principle of seismic stratigraphy,geo- logy,drilling data and analysis data by making use of a discrete operation of geometric mapping point by point,and computes comprehensively the ero- sional thickness with drilling data to determine a limited range of erosional re- gion.The advantage of the method is that original thickness of stratum can be recovered more reasonably.Good result has been achieved in certain cases in both eastern and western china.
