地震属性分析技术主要包括 3方面, 一是地震属性的提取, 即利用各种分析方法从地震数据中提取与岩性和储层物性等有关的信息, 拓展地震信息在油田开发领域中的应用; 二是地震属性的优化处理, 就是从众多地震属性中挑选出与研究目标关系最密切、反映最敏感的少数属性, 减少信息的重复和冗余; 三是储层参数转换处理, 即根据油田实际情况, 结合工区内测井资料的解释成果, 利用优化后的属性参数实现储层参数转换。

Seismic attribute analysis mainly consists of three steps. The first is extraction of seismic attributes, which picks information associated lithology and physical properties of reservoirs on seismic data by using various analysis methods,to extend the application of seismic data in the exploitation of an oil field. The second is optimization of the seismic attributes, that is to sort out attributes that are the most closely associated with and the most sensitive to the target, to reduce the repetition and redundancy of information. The third is the inversion of reservoir parameters with optimized seismic attributes. In this step the practical situation and interpreted logging data of the oilfield will be taken into account. An overall evaluation for the reservoirs should be derived to provide a reliable basis for the rollover exploration and exploitation of the oilfield.
