摘　　要：大港油田张东地区沙河街组地层地质条件复杂,储层厚薄不一,物性变化大,储层与非储层在声波曲线上没有明显的差异,要搞清该区储层特征分布、沉积类型、沉积相带展布及物源区,使用常规反演技术存在困难,因此,在该区采用了基于模型的拟声波曲线重构地震反演技术及多种地震属性提取技术的联合应用,结果使储层的可辨识性与反演预测结果的可靠性得到明显的提高,并获得显著的地质效果。The geological conditions of the Shahejie stratum in Zhangdong area of Dagang Oilfield are complex. It＇s difficult to understand clearly the reservoir characteristics, sediment type, sediment facies distribution, and the provenance because there is no obvious difference between reservoirs and non-reservoirs in the sonic log curve. The application of the reconstructed-log seismic inversion technology and seismic attributes are necessary. And they improved the reliability of the evaluation.
