基于地震属性各向异性的火山机构识别技术
|
摘要
本文通过对地震资料的分方位处理,分别提取各方位的地震属性,筛选出最具代表性的地震属性,通过属性方位椭圆拟合,求取该属性椭圆的"扁率",用椭圆"扁率"来表征储层的各向异性,并在此基础上识别火山机构.本文提出了基于地震属性各向异性的火山机构识别方法,利用叠前地震资料分方位提取地震属性,并对方位地震属性值进行椭圆拟合,利用椭圆扁率来表征各向异性的大小,并基于此来识别火山机构.本文对方法的流程进行了详细阐述,对方法的适用条件作了简要的说明,并用实际地震资料进行了效果检验,对检验结果进行了对比分析,取得了较好的效果.
By seismic data processing in different azimuths the seismic attributes of all azimuths are extracted and the most representative ones are filtered out in this paper.By attribute orientation ellipse fitting,the oblateness of the property ellipse is obtained to characterize the anisotropy of the reservoir.On this basis,volcanic edifice is identified.Using the different azimuths of prestack seismic data to extract seismic attribute,and fitting seismic attribute orientation ellipse,the oblateness is used to characterize the size of anisotropy and serves as the basis to identify volcanic edifice.In this paper,the method of volcanic edifice identification based on the anisotropy of seismic attribute is proposed with detailed elaboration of the flowchart and brief description of application conditions and the effect is examined,compared and analyzed with actual seismic data,which show good results.
