利用岩芯观察、物性分析、铸体薄片、压汞分析等方法,对兴隆台油田马58~马64井区沉积特征、岩石学特征、储层特征、孔隙结构等进行了细致研究。结果表明,马58~马64井区目的层段储层岩石类型主要为长石砂岩;沉积微相包括水上分支流河道、河道间、决口扇微相,属于河流三角洲分流平原亚相沉积;储集空间主要为原生粒间孔和次生溶蚀孔,以细~微孔喉为主。研究区内孔隙度和渗透率的相关性较好。影响储层物性的主要因素有填隙物、孔隙结构、沉积微相、粘土矿物等。

Study of sedimentology, petrology and pore structure of the reservoir by core observation, property analysis, cast thin and mercury analysis and so on indicates that reservoir in the Ma58-64 well area, Xinglongtai oilfield is composed mainly of arkoses of multiple sedimentary microfacies such as aquatic distributaries channel, interchannel, crevasse splay microfacies which belong to the river delta. The pore types include residual inter-particle pores, secondary dissolution pore predominated by fine-tiny pore throat. There is direct relationship between porosity and permeability. The reservoir properties are mainly affected by interstitial material, pore structure, sedimentary microfacies and clay minerals etc.
