摘　　要：地震属性种类繁多,利用属性预测储层也会产生多解性。以三道桥地区为例,根据过QG1井-QG101井-QG102井的油藏剖面,设计含油气层储层及不含油气层储层的2个模型进行正演模拟对比分析,得出振幅类属性对储层含油气性敏感,再沿地层切片提取相应的瞬时振幅属性及峰态属性进行分析,其平面形态与已知井的油气显示符合度较高,为后续的储层预测提供了质量较高的参考资料。There were many different kinds of seismic attributes and using the attributes to predict reservoir would result in multiple solutions. Illustrated by the case of Sandaoqiao Area,two models( one was designed for the reservoir containing oil and gas,the other was without bearing oil and gas) were established according to the reservoir profiles of Well QG1,Well QG101 and Well QG102. Based on the analysis of forward modeling,it is summarized that the derived amplitude attribute is sensitive to the oil-gas content of reservoir. A corresponding instantaneous amplitude is extracted along the strata slicing and it is compared with kurtosis attribute,its flat shape has high coincidence degree with oil show of the known well. It provides a high quality reference for consequent reservoir prediction.
