摘　　要：粒度是沉积物的重要结构特征,通过粒度资料分析沉积物的搬运方式和水动力条件,能有效判断储层的沉积环境。在岩心观察、薄片鉴定、粒度分析、测井数据分析的基础上,利用多种方法对馆陶组疏松砂岩储层的粒度特征及沉积环境进行了分析与探索,并建立了浅水辫状河三角洲和粒度概率累计曲线演化模式,该研究成果可以为疏松砂岩储层特征分析提供一定的理论依据,从而指导研究区乃至渤海湾盆地疏松砂岩储层的保护和治理。Grain size is an important structural feature of sediments.Analyzing the transport mode and hydrodynamic conditions of sediments through grain size data can effectively judge the sedimentary environment of reservoirs.On the basis of core observation,thin section identification,grain size analysis and log data analysis,this paper analyzes and explores the grain size characteristics and sedimentary environment of loose sandstone reservoirs in Guantao Formation using various methods,and establishes the evolution model of shallow braided river delta and grain size probability cumulative curve.The research results can provide a theoretical basis for the analysis of loose sandstone reservoir characteristics,It can guide the protection and treatment of unconsolidated sandstone reservoirs in the study area and even in the Bohai Bay Basin.
