摘　　要：勘探开发实践表明,阜东斜坡带河道砂岩储集层发育,油源充足,是有利的增储阵地。本文提出了综合识别斜坡带河道砂岩油藏的三种系列方法:(1)运用频谱分解技术的调谐体振幅谱识别薄地层的横向分布特征,优选对砂体响应敏感的频率段分析储集层的分布规律;(2)通过模型正演建立均方根振幅属性与河道砂体物性及厚度变化关系;(3)结合该区录井见显示井层所反映的属性与对应电性数据之间的关系,编制多维交汇图版,确定含油气性参数标准及门槛值,来定量识别研究区河道砂体油藏的展布特征。为有效识别阜东斜坡带侏罗系河道砂岩油藏奠定了基础。Exploration and development practice dictates that, Fudong Slope with channel sandstone reservoir developed and of sufficient oil source is advantageous to increase reserve. Three series methods were put forward to recognize the channel sandstone reservoir of slope, providing the foundation for the effective recognition of Jurassic channel sandstone reservoir in Fudong Slope. The first one is using tuning amplitude spectrum of spectral decomposition technique to recognize the transverse distribution characteristics of thin-layer, optimizing the sensitive frequency for sand responses in order to analyze the reservoir distribution rule, the second one is establishing the relationship between RMS with physical property and thickness of channel sand-body by forward modeling, the last one is constructing the multidimensional intersection chart by combining the relationship between the attributes of showing-well layer reflected and its corresponding electrical data, to determine the parameter standard and cut-off of oil-gas-bearing possibility. Then the distribution characteristics of channel sand reservoir were identified quantitatively.
