摘　　要：地震地貌学是一门通过三维地震资料来恢复古地貌、古沉积及其他地质信息的综合学科。川中地区下三叠统飞仙关组的鲕滩发育与沉积前的古地貌密切相关,为了准确地划分出高能鲕滩储层,可运用地震地貌学来研究飞仙关组储层。为此综合钻井、测井资料,运用地震相、地震层序、层拉平古地貌分析技术来识别飞仙关组沉积相带的边界、纵横变化、台缘带高能滩相的发育情况及古地貌变迁过程,并根据地震属性分析结果和古地貌特征,预测飞仙关组台缘带鲕粒滩的范围。结果表明,采用地震地貌学分析技术能较准确地预测飞仙关组高能鲕滩储层。Seismic geomorphology is a comprehensive discipline that 3D seismic data are used to restore palaeogeomorphology, ancient sedimentary and other geological information. And the development of the oolitic beach of lower Triassic Feixianguan formation in the central of Sichuan basin is closely related to palaeogeomorphology before deposition, so seismic geomorphology can be used to predict paleotopography for dividing highenergy oolitic beach reservoir. With the drilling and logging data, seismic facies, seismic sequences and layer flattering technique can be applied to recognizing the boundary and the vertical and horizontal change of sedimentary facies belt, the development of high energy oolitic beach and palaeogeomorphology transition processes of Feixianguan formation. What＇s more, combining seismic property analysis with palaeogeomorphologic characteristic, the range of later platform margin oolitic beach in the Feixianguan formation can be greatly estimated. In a word, the results show that the seismic geomorphology is an effective way to predict high energy oolitic beach reservoirs.
