层序地层学的精华就是综合应用露头、钻测井和地震资料进行层序地层分析。因此 ,在缺乏以陆上暴露不整合面为特征的层序界面的湖相沉积中 ,如何应用测井资料进行层序划分就成为层序地层学研究中一个重要环节。本文以柴达木盆地金达 1井第四系为例 ,介绍了一种综合利用岩芯、岩屑和电测曲线等测井资料 ,通过相对古水深曲线的建立 ,来进行层序地层分析的快速简便的方法。
The essence of sequence stratigraphy is the comprehensive application of outcrops, drilling logs and seismic data for sequence stratigraphy analysis. Therefore, how to apply well logging data to sequence stratigraphy has become an important step in the study of sequence stratigraphy in lacustrine sediments lacking sequence boundaries characterized by land-exposed unconformities. Taking the Quaternary of Jinda 1 well in the Qaidam Basin as an example, this paper introduces a comprehensive utilization of logging data such as core, cuttings and electrical measuring curves. Through the establishment of relative paleo-water curves, the stratigraphic sequence analysis Quick and easy way.
