基于地震多属性分析的深层浊积扇刻画研究

渤海辽东湾地区下第三系东营组存在大量各种类型的水下浊积扇，这些浊积扇体都是油气勘探最有利的目标之一。但由于埋藏较深，且只有少量的探井可供利用，因此，对这些浊积扇的研究只能依靠地震资料来进行。利用LD22–1 地区地震资料上提取的多种类型的地震属性，研究了该地区深部两种典型的浊积扇体及其内幕特征，不但分析了它们的地质特征，而且还分析了它们在不同类型地震属性上的表现特征，并从物理意义和地质意义两方面分析了为什么会出现这种表现特征，并得到了12 种对浊积扇体识别刻画敏感的地震属性。

Study of Deep Layer Turbidite Fan Detection Based on the Seismic Multi-attribute Analyses

There are various types of deep layer turbidite fans in Paleogene Dongying Formation from Liaozhong structure zone of Bohai Bay of China.These turbidite fans are the most potential play of oil & gas exploration.They were buried deeply,and few exploration wells can be used.Their research of these turbidite fans must rely on seismic data.This paper studies the two representative turbidite fans and their internal feature using polytype seismic attributes extracted from the seismic data of the LD22-1 area.We analyze not only their geologic characteristic,but also the display feature in the different seismic attributes,and the reason why they would show such feature from the physical and geological significance.Eventually,12 seismic attributes sensitive to the identification of turbidite fan are obtained.
