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。
通過運用地震、測井等方法，結閤巖心和薄片的鏡下識彆，總結瞭研究區沉積相的識彆標誌，把塔中地區鷹山組的沉積相劃分為開闊檯地、跼限檯地、檯地邊緣，併對檯內灘的展佈和厚度進行瞭精細的分析；鷹山組地層由下到上為雲巖段、雲灰巖段、灰巖段，沉積序列為嚮上變深的沉積鏇迴，併對沉積模式進行瞭總結，從檯地到盆地方嚮，主要為跼限檯地-開闊檯地-檯地邊緣-盆地的沉積模式。

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.
