通过铸体薄片、储层物性、压汞及扫描电镜等资料对储层特征进行分析,研究结果表明:储层岩石类型以石英砂岩为主,有矿物成熟度高而结构成熟度低的岩石学特点,总体物性较差,属于典型的低孔低渗储层。在明确储层测井响应特征的基础上,建立了合适的储层参数模型,计算了泥质含量、孔隙度、渗透率、含水饱和度、束缚水饱和度等储层参数,其中孔隙度、含水饱和度、束缚水饱和度与实验分析结果吻合较好。在这个基础上进一步解释没有取芯的井。
The reservoir characteristics were analyzed by means of thin slices of castings, physical properties of reservoirs, mercury intrusion and scanning electron microscopy. The results show that the reservoir rock types are mainly quartz sandstone with high maturity and low maturity Characteristics, the overall poor physical properties, is a typical low-porosity and low permeability reservoir. Based on the well logging response characteristics, a reservoir parameter model was established and the reservoir parameters such as clay content, porosity, permeability, water saturation and irreducible water saturation were calculated. The porosity, Water saturation, irreducible water saturation agree well with experimental results. On this basis, further explain the non-coring wells.
