【摘要】 三维可视化技术是一种全三维地震资料解释方法,有效地将地质知识应用于地震解释的先进手段,它可以提高解释人员从三维地震中快速获取地质信息的能力。应用帕拉戴姆公司的VoxelGeo三维可视化解释技术,在三维数据体内部直接工作,对研究区块的构造、地层和振幅特征进行综合研究,通过三维快速扫描,调节透明度,进而识别出异常体。在此基础上进行顶底雕刻,获得砂体的厚度变化,从而揭示河流相砂体储集体的空间展布规律。该方法在研究区域的应用效果比较明显。更多还原

【Abstract】 Three-dimensional visualization technology is a full three-dimensional seismic data interpretation method,which effectively applies the geological knowledge to the seismic interpretation method.The method can improve the interpreters’ ability of obtaining geological information from 3Dseism.Applying Paradigm’s VoxelGeo visualization techniques,this paper studied the characteristics of the structure of this section,the stratigraphy and the amplitude.By the rapid three-dimensional scanning,the transparency was adjusted and then the anomaly was identified.On this basis,the bottom was curved to get the changes in thickness of sand body so as to reveal the rule of the fluvial sandstone reservoir spatial distribution.This method is obviously effective in the the application of the study areas.更多还原
