摘　　要：地震相分析是储层预测的一项关键内容,其精度与合理性对勘探开发具有重要影响。由于地质条件复杂性、地震资料质量以及人为解释的主观因素等原因,导致常规地震相分析往往具有较强的多解性,不利于地震相的定量表征。提出一种地震相综合数字表征方法,其结合同相轴反射特征统计序列分析、灰度共生矩阵纹理属性、Hu不变矩参数方法,从内部结构与外部特征角度对地震相进行刻画,以期实现地震相的精确数字化表征,为地震相定量分析奠定良好基础。实际地震相资料的检验效果表明,该地震相综合表征方法可有效提供对地震相的定量表征,为今后地震相定量化精确分析提供了新思路。As a key component of the reservoir prediction,the accuracy and rationality of seismic facies analysis have an important impact on the oil&gas exploration and development.Due to the complexity of geological conditions,the quality of seismic data and the subjective factors of manual interpretation,conventional seismic facies analysis tends to have multi-solutions,which is not conducive to the quantitative characterization of seismic facies.Therefore,a comprehensive digital characterization method of seismic facies was proposed.And it combined with the statistical sequence analysis of the event reflection features,the texture attributed based on gray level co-occurrence matrix and the Hu invariant moments to delineate the seismic facies through the internal structures and external features.The research aimed to achieve accurate digital characterization of the seismic facies with all these efforts,paving the way for quantitative analysis of seismic facies.The application result of actual seismic records indicates that this comprehensive characterization method of seismic facies can effectively provide quantitative characterization of seismic facies.And it offers a new way for accurate quantitative analysis of seismic facies in the future.
