【摘要】 地震地貌学是一种新的地震相分析与表征方法,研究的是沉积特征在沉积等时面上的地震映像。它与地震岩石学一起构成了地震沉积学的主体。以L区为例,介绍了地震地貌学方法的基本工作流程、关键技术及其在沉积分析和储层预测方面的应用。地震地貌学强调在相对地质年代域中对沉积体成像,表征了地震相的平面反射形态。通过地震地貌学的沉积解释,容易把控沉积体的展布范围及其在沉积体系中的发育部位。沉积体的地震地貌学解释结果反投影到反演剖面上,可实现相控下的砂体雕刻,使属性分析和反演达到有机结合,从而提高沉积体和储层的预测精度。更多还原

【Abstract】 Seismic geomorphology is a new method for seismic facies analysis and characterization,which aims at studying the seismic imaging of sedimentary characteristics on the isochronal sedimentary surface.The main of seismic sedimentology is composed of seismic geomorphology and seismic petrology.Taking Block L as example, we introduced the workflow and key techniques of seismic geomorphology, and its application in sedimentary analysis and reservoir prediction.Seismic geomorphology emphasizes the imaging of sedimentary bodies in relative geologic age domain,and characterizes the plane reflection pattern of seismic facies.The sedimentary interpretation by applying seismic geomorphology easily understands the distribution of sedimentary bodies and its development position in sedimentary system.Projecting the interpretation results back to the inversion profile can realize the sculpture of sand bodies,organically combine attribute analysis and inversion,and improve the prediction accuracy of sedimentary bodies and reservoir.更多还原
