摘要

在阐述M agra提出的泥岩压实曲线法恢复地层剥蚀厚度方法原理的基础上, 通

过对泥岩压实曲线反映地层间断的6种形态模式和东濮凹陷泥岩压实曲线的形态特征的分

析, 论述了该方法在东濮凹陷的适用性。选择东濮凹陷100余口井的泥岩压实曲线应用该方

法计算了东营组地层剥蚀厚度, 结果与盆地模拟拟合的结果相近, 证明了该方法的可行性。

Abstract

Based on the desc ription of the estim ation m ethod of
erosion sedim ent th ickness by the sha le com paction curv e
m entioned or ig ina lly by M ag ra, th is paper d iscussed six
m ode ls of the form ation discontinuance demonstrated by the
sha le com paction curve. The app licab ility of this m ethod in
Dongpu depression is expounded through the charac teristics
analysis o f the sha le com paction curve. The erosion sed im ent
thickness o f Dongy ing fo rm ation is estim ated in te rm s of this
m ethod by e lecting shale compaction curve over 100 w e lls in
Dongpu Depression. The results from this m ethod and from
the basin m ode lling are qu ite sim ilar, wh ich proves tha t this
m ethod is re liab le.
