Seismic data are an integrated reflection of the sedimentary interfaces and processes of paleo formations. In this study, seismic geomorphology was applied to analyze and reconstruct the paleogeomorphology of the sedimentation of the Cambrian Longwangmiao Formation in the central Sichuan area by combining three-dimensional (3D) seismic data, a large amount of drilling data, logging data, cores and thin sections. It is believed that the thickness of the Cang-2 member reflects the paleogeomorphology during the sedimentation of the Longwangmiao Formation. Forward seismic modeling was used to select the seismic physical attributes sensitive to the Cang-2 member, which were then used to reconstruct the paleogeomorphology during the sedimentation of the Longwangmiao Formation. The results of this study show that the larger the amplitude of the bottom trough of the Longwangmiao Formation, the higher the landform during the sedimentation period. Therefore, the Caledonian paleo-uplift had already taken shape before the sedimentation of the Longwangmiao Formation, creating a paleo-geomorphologic pattern containing two uplifts and one depression. The geomorphologic distribution controlled the development of the shoals and reservoirs. The geomorphic highlands not only contained shoals with large areas and thicknesses but were also susceptible to superimposed syngenetic and quasi-syngenetic exposures, which provided preferential flow channels for atmospheric fresh water in the later period and caused the reservoirs to be subjected to more intense karstification. Due to the differences in the potential energy of the topography, the quality of the reservoirs in the NW slope zone is the best, followed by that in the NW high zone and the SE sub-high zone, while the shoals and reservoirs of the sedimentary geomorphic lowlands are poorly developed.

地震数据是沉积界面和古地层过程的综合反映。在这项研究中，地震三维地貌被用来结合三维（3D）地震数据，大量的钻井数据，测井数据，岩心和岩心来分析和重建川中地区寒武纪龙王庙组的沉积古地貌。薄薄的部分。认为Cang-2的厚度反映了龙王庙组沉积过程中的古地貌。用正演地震模型选择对Cang-2成员敏感的地震物理属性，然后将其用于重建龙王庙组沉积过程中的古地貌。研究结果表明，龙王庙组底槽幅度越大，沉积期地貌越高。因此，加里东古隆起在龙王庙组沉积之前就已经形成，形成了一个包含两个隆起和一个凹陷的古地貌格局。地貌分布控制了浅滩和储层的发育。地貌高地不仅包含面积大，厚度大的浅滩，而且易受同生和准同生叠加的影响，为后期的大气淡水提供了优先的水流通道，使水库遭受了更强烈的岩溶作用。由于地形势能的差异，
