油气勘探开发目标大多受构造岩性等多种地质因素控制,地震属性一般也都受多种地质因素的影响。根据研究目标情况,在地震属性―地质分析的基础上,利用地震属性提取技术和信息分解技术可以得到与研究目标关系密切的多属性地震信息。在地震属性优选的基础上,运用MD I综合预测系统可以实现地震多属性与储层信息的结合和运用多种定性、定量化模型以及利用多属性信息融合,可以实现多属性综合储层油气预测。指出由于对信息进行优化组合能够导出更多的有效信息,可以大大减少预测的多解性,实钻结果在很多地区都获得了油气层,显示了多属性综合方法预测的优势。

The objects of hydrocarbon exploration and development are mostly controlled by multiple geofactors such as structure and lithology. Seismic attributes are also commonly affected by these geologic factors. Based on seismic attributes and geology analysis, multiple seismic attributes that are tied up to the studying objects can be obtained by technologies on seismic attributes extraction and information decomposition. Based on seismic attributes optimization, MDI Comprehensive Prediction System can realize hydrocarbon prediction with multiple attributes by integrating them with reservoir information, applying a great variety of qualitative or quantitative models and fusing these attributes. For common or united advantages have been used, more effective data can be educed by optimization and combination of these information, which can reduce the multiple resolutions of hydrocarbon prediction greatly. Oil-gas layers have been found by drilling in many areas, showing the advantage of the method of hydrocarbon detection by integrating multiple seismic attributes.
