四川盆地威东—安岳地区上三叠统须二段湖泊滩坝砂体特征

摘要

文章系统研究了四川盆地威东—安岳地区上三叠统须家河组须二段湖泊滩坝砂体的岩性、沉积构造和结构特征,电性和地震反射特征,物性、含油性特征及其展布特征,讨论了该地区须二段滩坝砂体的石油地质意义,认为须二段滩坝砂体属于优质储层,近油源且具生储盖组合,含油性良好,应进一步勘探开发.%This paper summerizes systematically features of lithology, sedimentary structure, texture, e-lectric assemblages and seismic reflection section, physical property and oil bearing property, beach and bar sandbody's distribution of Member 2 of Xujiahe Formation in Weidong-Anyue area and discusses significance of the sandbody to exploration of oil and gas reservoir.
