英文摘要	以浊积朵叶体沉积为例,介绍了砂体融合现象的类型与形成原因,讨论了砂体融合现象对沉积环境及砂体叠置样式的指示作用,并应用砂体融合比定量描述了砂体之间相互融合的程度.在以砂泥为主的碎屑沉积中,砂体之间的相互融合非常普遍,其包括砂体对泥质隔夹层的侵蚀并与其他砂体融合两个方面.对已有文献的统计分析表明,砂体融合比在不同的构型层次有显著差异,在此基础上,用基于目标的建模方法建立了3组砂地比、单砂层尺寸相同但具有不同层次与不同砂体融合比的朵叶体三维模型.对模型的连通性分析表明:模型引入的沉积层次越多,连通性越差;对沉积层次一致的模型而言,砂体融合比越高,连通性越好.; Taking turbidity lobe deposits as an example,the types and formation mechanisms of sandstone amalgamation were discussed,the indications of sandstone amalgamations to sedimentary environment and stacking pattem of sand bodies were investigated,and "amalgamation ratio" was employed to quantitatively describe the degree of sandstone amalgamation.Sandstone amalgamation is a common sedimentological phenomenon in sand/mud dominated clastic deposits,which generally consists of two processes:erosion of inter-sand mudstone barriers and amalgamation of sandstone beds which were previously separated by the mudstone barriers.Statistics analysis suggests that amalgamation ratio varies greatly in different hierarchical levels of structures.Based on these analyses,three sets of conceptual lobe 3D models with identical NTG (net to gross ratio) and bed sizes but different hierarchies and different amalgamation ratio using an object-based modeling approach.Static connectivity analysis of these models suggests that the more the hierarchical levels,the worse connectivity the model has;for models with identical hierarchical settings,the higher the amalgamation ratio,the better the connectivity.; 中国博士后科学基金; 中国科学引文数据库(CSCD); 2; 205-212; 44
