摘要
地震属性信息是蕴含在地震反射波中的有用信息,随着勘探开发力度的加强及油气藏精细描述的开展,地震属性信息已经引起地球物理、地质工作者的高度重视,尽管现代地震技术发展很快,信噪比和分辨率都有所提高,但仍不能忽视地震信息是反映地下地质情况的这一基本属性,它能从多方面反映地下特殊地质现象、沉积现象、流体特征等。以克拉玛依五区上乌尔禾组油藏为例,全面介绍了各种常用地震属性信息的概念及其油气田勘探开发中的作用和应用效果。
Seismic attribute in fo rmation is the useful information in volved in seismic reflection wave.As incr easing intensity of explo ration and development and performing detailed reserv oir characterization,the seismic attribute in formation is paid greatly attenti on to by geophysi-cists and geologists at home and broad.Despite the rapid dev elopment of modern seismic technology and improvement of sig nal-to-noise ra-tio and resolution,the seismic attribute information re flecting special in-situ geological phenomenon,sedimentary feature and fluid behavior,etc.,shoul d not be ignored.Taking Upper Wuerhe formation in District No.5as an ex ample ,this paper pre sents the con cepts of various com-mon seismic attribute infor mation and their applicable effects in oil/gas field explo ration and develop m ent.
