【摘要】 随着三维地震采集、处理、解释技术水平的提高及其广泛应用,在高精度等时层序地层格架内利用三维地震的属性切片技术刻画沉积体的三维几何形态及其沉积演化过程,已成为地震地质研究越来越受到关注的一个研究方向,并逐渐衍生为一门新的学科──地震沉积学。地震沉积学的应用一方面要充分理解地下沉积体宽厚比的"不均衡性",另一方面又要客观辩证地评价地震沉积学对于"薄层"沉积体的分辨能力。陆相地层地震沉积学应用要比海相地层复杂,陆相地震沉积学研究应该形成其自身的特点和技术方法体系。地震沉积学应用的关键是建立高精度等时层序地层格架、以正确的沉积相模式为指导及精细标定地震属性的地质含义,要强调多学科、多因素、多技术手段的联合应用与约束。更多还原

【Abstract】 As the 3D seismic acquisition,processing and interpretation technology being continuously improved and widely used,more and more attention is paid to depicting the 3D geometric shape and sedimentary process of depositional bodies with 3D seismic attribute slices within high resolution sequence stratigraphy frame,which has formed an important study direction and leads to the birth of a new subject-seismic sedimentology.We should understand the ’imbalance’ between horizontal width and vertical thickness of the depositional bodies in order to better apply seismic sedimentology and evaluate the 3D seismic resolution capability of ’thin bodies’ objectively.There is much difference between continental and marine seismic sedimentology,so the continental seismic sedimentology should develop its own characteristics and theoretical system.Finally we pointed out that high resolution sequence stratigraphy frame,correct deposition facies model and calibrating the geological meaning correctly of seismic contribute should have 3 key steps in the application of seismic sedimentology.We should focus on the integrative application and inter-feedback of multi-subjects,multi-factors and multi-technologic methods.更多还原
