摘 要:随着储集层预测技术的发展,提取众多的属性参数进行判断已成为地震解释的重要手段,在进行储集层预测和评价时,通常使用与储集层预测有关的各种地震属性,以各种方法从地震数据体中提取的一系列地震属性包含有丰富的地下地质信息,不同的地震属性值可能与某些地质参数具有很大的相关性,因此利用地震属性参数可以有效地预测岩性和有利储集层,描述油藏特征及孔隙度变化,寻找死油区。描述了地震属性中的振幅、阻抗、频率及能量衰减四种基本类型参数的特征意义,并对泌阳凹陷核二段白云岩区进行了振幅、频率、衰减、阻抗等属性提取分析,成功地预测出白云岩的分布范围。With the development of the reservoir prediction technique,the discrimination of reservoir through extracting more attribute parameters has been an important method in seismic interpretation.When prediction and estimation of reservoirs,we usually use all kinds of seismic attributes related to reservoir prediction,and those extracted from seismic data volume with various methods and abundant geologic information.There are probably lots of relativities between the varied seismic attributes and some of geologic parameters,so using the varied seismic attributes could effectively predict the lithology and favorable reservoir,describe reservoir characterization and the variation of porosity and find out bypassed oil region.This paper describes the basic types of seismic attributes such as amplitude,impedance,frequency and energy attenuation and their characteristic significances,analyzes these seismic attributes extracted from dolomite area of H-2layer in Biyang sag,and predict successfully the scope of the dolomite reservoir distribution.
