摘　　要：地震沉积学在沉积体系研究中具有特殊的优势,为了对海底扇储层沉积体系进行更为精确细致的刻画,利用地层切片、分频解释两项关键技术对海底扇水道亚相进行了地震沉积学研究。在研究区内层序地层等时格架的基础上制作了一系列地层切片,这些切片提供了海底扇水道连续沉积的地震图像,刻画了海底扇水道沉积体系在不同时期的展布特征及演化过程,同时分频成像能有效提高水道解释精度。Seismic sedimentology had special advantages in depositional systems research.In order to depict the depositional system of submarine fan reservoirs more accurately,seismic sedimentary study was carried out by using strata slice and frequency division interpretation of submarine fan channel.Based on sequence stratigraphic framework,a series of strata slices were prepared.Those strata slices provide continuous deposition of submarine fan channel of seismic image and characterize the deposition of submarine fan channel system for the distribution characteristics of different periods and evolution,meanwhile,frequency division image could enhance the interpretation accuracy of channels.
