摘要：

所谓地震速度相就是将速度参数引入地震相研究之中的一种方法,主要包括两个方面的内容:一是利用钻井资料,作速度与岩性的对应性研究,提取岩性信息;二是利用连井地震剖面进行桥式对比,找出速度色标段与岩性的对应关系,划分速度相。运用此方法,可将滇西瑞丽盆地中新统划分为丘状杂乱前积高速相、席状亚平行中速相、席状平行低速相、丘状杂乱高速相等4种地震速度相,以及与此相关的4种沉积相:扇三角洲相、滨浅湖相、半深湖相、近岸水下扇相。

Abstract:

Seismic-velocity facies is that velocity data is used in conventional seismic facies study.This includes:1 using drilling data in the study of correspondence between velocity and lithologic characers;2 using double well seismic profile in bridge type correlation in order to find out the correspondency between velocity colour scale and lithologic characters and determine different velocity facies.The Miocene in Ruili Basin,Western Yunnan Province could be divided into hilly complex foreset high velocity facies,sheet subparallel mid-velocity facies,sheet parallel low velocity facies,hilly complex high velocity facies and 4 relative sedimentary facies such as fan deltaic facies,shore-shallow lake facies,mid deep lake facies and near shore subequeos fan facies.
