摘要
在阐述Magra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。
Based on the description of the estimation method of erosion sediment thickness by the shale compaction curve mentioned originally by Magra,this paper discussed six models of the formation discontinuance demonstrated by the shale compaction curve.The applicability of this method in Dongpu depression is expounded through the characteristics analysis of the shale compaction curve.The erosion sediment thickness of Dongying formation is estimated in terms of this method by electing shale compaction curve over 100 wells in Dongpu Depression.The results from this method and from the basin modelling are quite similar,which proves that this method is reliable.
