| 摘 要： | 沉积相研究对于现代油气勘探开发具有重要意义。通过沉积相的研究,建立不同沉积相模式,对深入分析沉积微相对油气的控制关系具有指导作用。文章对川西南部地区上三叠统须家河组须二段砂岩粒度特征进行了系统研究,并针对不同曲线形态、粒度参数特征作了具体分析。同时,参考萨胡粒度判别函数以及CM图解对研究区沉积相进行了判别,表明研究区须家河组须二段主要受牵引流作用,为辫状河三角洲相特征。

| Abstract: | Research of sedimentary facies is important for modern oil and gas exploration and development. Model building of different facies and micro-facies analysis will guide establishment of the control factors of oil and gas. Particle size characteristics of the 2nd Member of Upper Triassic Xujiahe Formation are systematically researched and morphology of different curves and particle size parameters analyzed. Sedimentary facies in the study area are discriminated with Sahu discriminant function and CM diagram. The analysis results show that the sedimentary facies in the Upper Triassic Xujiahe Formation is mainly characterized by braided river delta, dominated by the traction current. |
