摘要

高分辨率地层学是一门新学科和新技术,其核心是地层基准面变化旋回的识别和对比。该文通过钻井、岩心、测井和地震资料的详细分析,对胡状集地区沙河街组沉积地层的中、短期基准面旋回进行了仔细研究,并从砂岩变化、颗粒粒度变化及测井曲线变化等方面进行描述、总结出该区高分辨率层序地层的堆积样式和沉积特征,为今后胡状集地区高分辨率地层研究提供了一种可借鉴的方法。

Abstract

High resolution stratigraphy is a new scientific

technology. Identification and comparison of cycle change

datum level are being its first researching problem.Based on a

careful analysis of drilling ,coring logging and seismic data ,

the authers research medium-short period datum level

Shahejie depositional beds of Huzhuangji region ,and describe

sandy shale , grain size and logging curve changes , sum up

depositional mode and character of high resolution sequence

stratigraphic ,in the region ,the researching result is used for

reference of high resolution stratigraphic research in

Huzhuangji region for the future.
