摘　　要：物理和数值模拟是深水重力流沉积过程研究的有效手段.利用实验室中不同类型水槽(水池)可模拟不同条件下的重力流沉积过程、海底地貌与重力流之间的相互作用过程,并据此展开相应的数值模拟分析,从而实现深水重力流沉积过程的定量分析.基于我国南海北部深水油气勘探开发目前所取得的地质认识,展开关于白云凹陷珠江组重力流流体转换过程和浅层富含生物碎屑的重力流沉积过程模拟、琼东南中央峡谷内浊积水道沉积过程模拟,有助于揭示深水区砂体的展布规律以及储层构型特征,指导南海北部下一步的油气勘探开发.Physical and numerical simulations are efficient techniques to study the sedimentary process of gravity flow.By various types of flumes（or/and tanks）,the sedimentary processes of deep-water gravity flows with different conditions,and the interactions between the submarine geomorphology and deep-water gravity flows,can be simulated.On the basis,the corresponding numerical simulation can be carried out to realize the quantitative analysis for the sedimentary processes of deep-water gravity flows.According to the previous achievements about the deep-water hydrocarbon exploration in the northern South China Sea,it is meaningful to conduct the simulation on the gravity flow transformation and sedimentary processes for thesubmarine fan of Zhujiang formation and the bioclast-rich turbidites of the shallow strata in the Baiyun sag,as well as the sedimentary processes of the turbidity channels in the central canyon of Qiongdongnan basin,which contribute to revealing the laws of sand-rich sediments distribution and the features of reservoir architecture,as well as guiding the deep-water hydrocarbon exploration and exploitation in the northern South China Sea.
