摘　　要：针对在密井网条件下提取薄储层地震属性信息时存在的问题,提出一种基于地质模式的多元地震属性储层预测方法.研究结果表明：该预测方法能够使井、震属性的相关系数由0.28提高到0.72;在提高井、震属性匹配程度的基础上利用多元逐步回归法降低了采用单一地震属性进行储层预测的多解性,进一步提高了目的层的砂岩厚度预测精度（达到0.89）,砂体的平面分布特征也更符合地质规律;在密井网条件下进行井间砂体定量预测行之有效.In the light of the problem exists in gathering the seismic attributes from the reservoir under the conditon of density well pattern, the predicting method of multiple seismic attribute reservoir is proposed on the basis of the geological mode. The study results show that the method can enhance the well-seismic attribute correlation coeffi- cient from 0.28 to 0.72; based on the increase of well-seismic attribute matched degree, by means of multiple gradual regression approach, the phenomenon of multiple solutions in the reservoir prediction with the help of the single seismic attribute is limited and then the prediction precision of the sandstone thickness of the target reservoir is further enhanced to 0. 89, the planar distribution characteristics of the sand bodies are more in tune with the geo- logical laws; it proves that the method is efficient to quantitative predict the interwell sand bodies under the condi- tion of the dense well pattern.
