摘要
在对岩心详细观察的基础上,通过时研究区杨大城子油层沉积物的结构、构造、颜色、组合韵律、垂向序列、电性响应、砂体平面展布特征的综合分析,认为研究区杨大城子油层总体上是-套河流相沉积。作为油气储集层的砂体主要是点坝砂体。
The Yangdachengzi oil-bearing member is composed of lithologic poolspredominantly.It is very important for the hydrocarbon exploration and exploitation forus to know the sedimentary environment of the Yangdachengzi oil-bearing member andthe genesis of the sand bodies.Based on the detail study of cores(including the structure,colour,composition and vertical sequence),log response,and the systhetic analysis of thedistribution of the sand bodies, the authors interpreted the Yangdachengzi oil-bearingmember as mainly fluvial facies and the hvdrocarbon reservoirs were considered as pointbar sand bpdoes.
