中文摘要：

针对伊通盆地大南凹陷双阳组储层的结构特点,以地质、测井及地震资料为基础,采用地震属性分析、波阻抗反演等方法,对储层分布特征及有效厚度进行预测。认为研究区双一段和双三段泥岩层为主要生油层,储层以双一段底砾岩及双二段砂岩为主;双阳组砂岩储层比较发育,多集中在西北和东南两大断层附近,从反演获得的砂体厚度可知,双二段岩层厚度相差较大,双一段的厚度则相对均一。

英文摘要：

This paper provides an overview of the prediction of reservoir distribution and effective thickness by means of seismic attributes analysis and wave impedance inversion based on geological,logging and seismic data in terms of the structural features of Shuangyang Formation in Danan sag,Yitong Basin. The Shuang-Ⅰ and Shuang-Ⅲ segment in the study area are the main source beds,reservoirs consist of Shuang-Ⅰ basal conglomerate and Shuang-Ⅱ sand rock;sandstone reservoir are well developed in Shuangyang Formation,which are mostly concentrated in the vicinity of the northwest and southeast fault. The inversion of sand body thickness shows that the thickness of Shuang-Ⅱ formation are quite different,while the thickness of Shuang-Ⅰ are relatively uniform.
