右江裂谷盆地呈现孤台与台盆相间分布的沉积格局，下二叠统可划分出６个三级层序。沉积背景不同，则层序充填序列、内部构型和成因格架各异。其中孤台层序发育主要受海平面变化和碳酸盐自旋回的控制，以碳酸盐岩为主，层序界面特征明显，通常缺失ＬＳＴ，海平面曲线具有跳跃、间断、不对称特点；台盆层序发育则主要受同沉积断裂活动控制，主要由硅质灰岩、硅泥岩和硅质岩构成，层序发育完整，海平面曲线呈现渐变、连续、对称特征，能客观地反映沉积盆地的连续变化史。右江裂谷盆地层序格架中的有利储集体主要包括：①孤台中受层序界面控制的古岩溶储层；②与ＬＳＴ相关的残积体（孤台）和混屑浊积岩（台盆）；③与ＴＳＴ有关的海侵型丘礁滩灰岩（孤台）和钙屑碎屑流沉积（台盆）；④与ＨＳＴ有关的丘礁滩灰岩、白云岩（孤台）和钙屑重力流沉积（台盆）；⑤碳酸盐孤台。
The Youjiang rift basin presents the sedimentary facies pattern of the isolated platform and the basin. There are 6 third-order sequences in the Lower Permian. Sedimentary background is different, the sequence filling sequence, internal structure and genesis of different causes. Among them, the development of the Orotai sequence is mainly controlled by the sea level change and carbonate spin-back. The carbonate rocks are the main features of the sequence and the sequence interfaces are obvious. Usually LST is missing. The curve of the sea level has jumping, discontinuity and asymmetry. The basin sequence development is mainly controlled by synsedimentary faulting, which is mainly composed of siliceous limestone, siliceous mudstone and chert, and the sequence is well developed. The sea level curve shows gradual, continuous and symmetrical features, which can objectively reflect the deposition The continuous history of the basin. The favorable reservoirs in the sequence framework of the Youjiang rift basin mainly include: (1) paleokarst reservoirs controlled by sequence boundaries in the orographic platform; (2) residual structures related to LST (solitary platform) and turbidite Basin); ③ TST-related transgressive shoal reef littoral limestone and calcareous debris flow sedimentation (basin); ④ HST-related mound reef limestone, dolomite (solitary platform) and Calcium slag gravity flow deposition (basin); ⑤ carbonate solitary Taiwan.
