含油气盆地剥蚀厚度恢复研究进展

Research on Eroded Srata Thickness Restoration in Petroleum Basin

地层剥蚀厚度恢复是含油气原始盆地恢复的重要内容,对定量研究盆地演化史意义重大。对利用地质判别推断、沉积速率与旋回、压实密度和热演化等四个方面的剥蚀厚度恢复方法进行了总结归纳,选取有代表性的方法进行探讨。通过比较,最后提出应根据研究区具体的地质特征选择适宜的方法,注意多种方法的综合运用来进行剥蚀厚度恢复。

Eroded srata thickness restoration is important content in original petroleum basin restoration, and it had signifi- cance to quantitative research basin evolution history. The article summaries four aspects which are geological inference, deposition rate or cyclothem, compaction density and thermal evolution. Some representative methods was selected to discuss and comparation. Finally, the appropriate method should be selected according to the specific geological characteristics of the study area. And attention should be paid to the integrated use of variours methods for eroded srata thickness restoration.
