Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.
进一步采用以第4层次基准面旋回中相当最大湖泛面的相转换面和具有区域性暴露侵蚀作用的层序边界面为等时地层对比框架的边界,对发育于MSC2—MSC4三个第4层次基准面旋回的第3层次基准面旋回内砂体进行了逐层等时对比,探讨第4层次等时地层对比格架内储集砂体发育分布规律,及储集砂体的非均质性特点,研究发现:①第4层次基准面上升初期发育的水下分流河道,砂体呈连续叠置、侧向迁移受限,纵向上呈长距离延伸的带状产出,砂体间泥、粉砂岩夹层少,储层非均质性相对较弱;②在第4层次基准面上升中期发育的水下分流河道侧向迁移活跃,纵向延伸过程中分流汇合作用强烈,以形成网状或席状连片砂体为主,但砂体间泥、粉砂岩夹层逐渐增多,储层非均质性增强;③第4层次基准面上升晚期和下降早期,不利于储集砂体发育,仅出现少量薄的水下分流河道、水下决口扇、远—河口砂坝砂体。
