摘要
基于混合沉积文献调研和苏北盆地金湖凹陷古近系阜宁组二段混合沉积研究,对比讨论了混合沉积的定义、混合沉积环境、混积岩分类以及混合沉积成因机理,提出了混合沉积研究存在的两个问题和四个研究方向;总结了金湖凹陷阜二段广义和狭义混积岩的发育特征,明确了干热咸化的水体和充足的陆源供给是阜二段发育混合沉积的基础,建立了阜二段混积岩相分布模式,并对混积岩油气研究的未来方向进行了展望。
According to literature survey and previous studies of mixing deposition in the second member of Paleogene Funing Formation in Jinghu Sag,it was discussed the definition,environment,classification and genesis mechanism of mixed sediments.And then it was proposed two existing problems and four research directions on the study of mixing deposition.It was concluded the development features of general and special mixing siliciclastic-carbonate sediments in the second member of Funing Formation in Jinghu Sag.So it was determined clearly the hot-salty water body and the supply of abundant terrestrial sources,which are the basis for mixing deposits in the second member of Funing Formation.Finally,a phase distribution model for the mixing deposits was established,and it was pointed out the future research direction.
