Application of Paleobathymetric Curve in the Sequence Stratigraphy of Well-logging Data

Geoscience Department, University of Petroleum, Changping Beijing 102200

摘要

摘要: 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。

Abstract: It is well known that integrated use of outcrop, well-logging and seismic data is the key to sequence stratigraphy. Therefore, how to identify the sequence boundary by well-logging in the lacustrine sediments which are lack in the unconformity is critical step to sequence stratigraphic analysis. With an example of sequencestratigraphy of Quaternary in well Jinda1, Qaidam basin, this paper presents the basic procedures of new approach for a stratigraphic subdivision of well logs into sequences by reconstruction of paleobathymetric curve. After the log facies analysis, six kinds of lithofacies have been recognized in Quaternary which are dark-grey shale, brown shale, grey silty shale, carbargillite, shaly siltstone and siltstone. For each Lithofacies association a sedimentologically coherent paleoenvironmental interpretation has to be established. Hence, a distinct paleobathymetric range is assigned to each lithofacies unit. Based on this relative paleo-waterdepth, paleobathymetric curve of Quaternary in well Jinda1 has been established from a vertical succession of lithofacies. This water-depth curve helps to identify stratigraphic sequence of different scales.This approach is based on the identification of bathymetry turnaround trends in the lithofacies succession. The maximum regressive surface is placed at the lowest waterdepth values on the smoothed bathymetry curve. The maximum regressive surface is identical to the sequence boundary. The maximum flooding surface is placed at the deepest bathymetry as the closest approximation. This horizon separates underlying transgressive half cycle from overlying regressive half-cycle. Based on the rules above, four sequences are identified in the Quaternary sediment of Jinda1 Well. Each sequence consists of two systems tracts separated by maximum flooding surface. It is clear that there are two scales of waterdepth cycle in the bathymetry curve. More frequent fluctuation in the bathymetry curve can be considered as the response to the high order stratigraphic sequence. At last, the prospective source rock, favorable reservoir and potential caprock have been predicted.
