摘要
为详细了解孤东地区古近系储层成因类型的物性特征,分别对其主要的储层成因类型———辫状河三角洲砂体、曲流河三角洲砂体、浅湖砂体和半深湖砂体的物性做了详细研究。通过对几种储层成因类型的孔隙度、渗透率及泥质含量的统计分析认为,辫状河三角洲砂体储层物性好;曲流河三角洲砂体储层物性较好;浅湖砂岩体和半深湖砂体储层物性较差。
In order to know physical properties of Eogene reservoir origin type in Gudong area clearly,the physical properties of the main reservoir origin types were studied in detail including sandbodies of braided-river delta, meandering-river delta, shallow lake and bathyal lake. By statistical analysis of their porosity, permeability and shale content,it is considered that the physical properties of reservoir of the braided-river delta sand-body are the best, and those of reservoir of the meade-ring-river delta sandbody are better, and those of reservoir of the shallow lake and bathyal lake sandbody are poor.
