摘　　要：目前,扇三角洲的研究主要集中在古地貌、沉积特征、储层测井评价、钻井工艺等方面,对扇三角洲地震地层构型的研究较少。文章以构造地质学、沉积学、地震勘探原理为理论指导,以茂名盆地黄牛岭组扇三角洲露头为研究对象,通过野外露头剖面观察与测量,划分扇三角洲辫状分流河道地质构型,并采用基于声波方程的高阶交错网格有限差分法开展了扇三角洲辫状分流河道不同叠置类型的地震数值模拟研究,基于黄牛岭组地震响应特征总结扇三角洲辫状分流河道的叠置模式,为扇三角洲的地震解释提供了依据。Recently,fan delta research is mainly focused on palaeomorphology,sedimentary features,reservoir logging evaluation,drilling process,etc.,with less research on fan delta seismic stratigraphic formations.This paper uses tectonics,sedimentology,and seismic exploration principles as a guide to study the fan delta outcrops of the Huangniuling Formation in the Maoming Basin,to delineate the geological configuration of the fan delta braided diversion channel through observation and measurement of the field outcrops,and to carry out seismic orthogonal simulations of the fan delta braided diversion channel of different superposition types using the high-order interlaced grid finite difference method based on acoustic equations.At the same time,the seismic response characteristics of the Huangniuling Group are analyzed to summarize the stacking pattern of the fan delta braided diversion channel,which provides a basis for the seismic interpretation of the fan delta.
