Physical simulation of formation process in distributary channels and debouch bars in delta 三角洲分流河道及河口坝形成过程的物理模拟
The more favorable reservoir sandbodies are submerged distributary channel sandbodies and debouch bar sandbodies on delta front 较有利的储集砂体为水下分流河道或河口坝砂体。
As getting incision of underwater distributary channel in different period , debouch bar keeps short time and low - development 由于受到不同期水下分流河道的切割,河口坝保持时间较短而欠发育。
The main sedimentary microfacies are submerged distributary channel , debouch bar , submerged natural levee and flood - plain splay . the research shows that the physical property of subermerged distributary channel sandbodies are the best and debouch bar comes second 长4 + 52长62油层砂体的沉积微相类型主要有水下分流河道、河口坝、水下天然堤和水下决口扇等,其中水下分流河道砂体的物性相对最好,其次为河口坝砂体。
And the delta genetic unit includes distributary channel , distributary bay , small lake of delta plain , swamp , distributary estuary bar , frontal delta mud and sandy density flow and so on . the fluvial system is composed of channel , channel side and flooding basin 其成因相包括分流河道、决口扇及决口河道、分流间湾、三角洲平原小型湖、沼泽、分流河口坝、前三角洲泥及砂质重力流等;该区河流体系由河道、河道边部及泛滥盆地等沉积组合构成。
