【摘要】 随着地震沉积学解释技术的快速发展,如何利用地震多属性参数研究地震层序切片,进而指导地震沉积解释重新引起了人们的关注。由于地震属性的多解性导致计算机自动分类存在着计算量大、地质意义不明确等问题,本文介绍了一种基于地震影像处理的地震相自动分类方法,采用地质意义明确且相互独立的三种地震谱属性(有效带宽、主频、主频振幅),对金山气田火石岭组上段进行地震相划分,取得了较好的效果。更多还原

【Abstract】 With the rapid development of explain technology of seismic sedimentology,how to make use of seismic multi-attribute parameters to study seismic sequence slice then to guide seismic sedimentary interpretation cause the attention of people.Due to the uncertainty of seismic attributes leading to a large amount of calculation of computer automatic classification and unclear geological significance,this paper introduces a kind of seismic facies automatic classification method based on the seismic image processing.The clear geological significance and independent of each other of three seismic spectral properties(effective bandwidth,frequency,frequency amplitude)are used to classified seismic facies in the upper of Jinshan gas filed Huohshi group,and good effects have been achieved.更多还原
