中文摘要：
储层的几何形态和空间展布预测是储层预测的主要内容.本文根据Curvelet变换的奇性分析特征及地震资料瞬时相位在追踪地质层位的优势,提出了基于Curvelet变换的地层结构提取方法.将提取的地层结构剖面和瞬时频率或其它与地层岩性相关属性联合显示,能更清晰、直观地解释有利储层的几何形态和空间展布特征.通过合成资料和实际数据的算例,验证了本文方法的有效性.
英文摘要：
The prediction of reservoir geometry shape and spatial distribution is the main content of reservoir prediction. According to the singularity analysis characteristics of the Curvelet transform and the superiority of seismic data instantaneous phase in tracing geological horizon, a strata/configuration extraction method is proposed, which is based on the Curvelet transform and instantaneous phase. The joint displays of the stratal configuration section extracted and instantaneous frequency or other lithology-related seismic attributes can interpret the favorable reservoir geometry shape and spatial distribution characteristics in a more clear and institutive manner. The synthetic data and real data processing results confirm the effectiveness of the proposed method.
