【摘要】 通过运用地震、测井等方法,结合岩心和薄片的镜下识别,总结了研究区沉积相的识别标志,把塔中地区鹰山组的沉积相划分为开阔台地、局限台地、台地边缘,并对台内滩的展布和厚度进行了精细的分析;鹰山组地层由下到上为云岩段、云灰岩段、灰岩段,沉积序列为向上变深的沉积旋回,并对沉积模式进行了总结,从台地到盆地方向,主要为局限台地—开阔台地—台地边缘—盆地的沉积模式。更多还原

【Abstract】 According to the methods such as seismic interpretation and logging,combined with core and thin slice microscopic anal ysis,this paper summarized the identification marks of sedimentary facies in the study area,divided sedimentary facies of Yingshan group in Tazhong area into open platform,restricted platform and platform edge,furthermore,made fine analysis on the distribution and thickness of intra-platform shoals.Yingshan group layer consists of dolomite,dolomitic limestone and limestone from bottom.Sedimentary sequences are deepen sedimentary cycle upward.Summary of depositional model showed that from platform to basin it is mainly the model of restricted platform—open platform—platform edge—basin.更多还原
