| 摘 要： | SZ地区上三叠统—侏罗系构造圈闭仅在局部有分布,该区域井资料少且只有二维地震资料,利用这些资料研究砂体在剖面上展布以及砂体连通性其可靠性差。本文利用模型正演技术,借助该区域二维剖面反射特征,利用井资料提供岩石物理参数,设计地质模型,进而研究和分析模型正演结果,最后结合钻测井资料以及地震反演结果,确定SZ地区砂体的展布特征及砂体尖灭点,从而明确了砂体连通性,以及砂体的剖面展布特征。

| Abstract: | This paper uses the method of forward modeling to indicate the reflection characteristics of the area of SZ,and it is useful for the sand-stone distribution to discriminate the seismic inversion.And also it is easy to discriminate lithological reservoir＇s sand-stone and full perception of the sand-stone distribution of SZ zone.The forward modeling methods for correction and identification are presented here.It is illustrated that this method is successfully used to interpret the complicated subsurface geologic body and understand the sandstone characteristic. |
