摘要
文章在系统收集和整理榆树林油田葡萄花油层资料的基础上,利用薄片观察和统计、扫描电镜观察分析、岩石物性(孔、渗)测定及压汞资料分析等方法,重点对葡萄花油层储层内岩石矿物成分、成岩作用类型、孔隙类型及孔隙结构特征进行了详细研究,为指导油气开发提供科学依据。研究表明:榆树林油田葡萄花油层为中孔、中渗储层,岩石以长石砂岩为主,具有结构成熟度中等,成分成熟度较低的特点;储集空间以残余粒间孔为主,亦见有次生溶蚀孔及晶间微孔;根据孔隙结构特征,将葡萄花油层储层分成4类。
Based on data of Putaohua layers of Yushulin oilfield,using many methods to research the textural characters, for example, thin section, statistic, scanning electron microscope, petrophisical data and Hg etc. Especially, researching component of minerals, type of digenesis and pore etc. Research indicated ,oil layers belong to moderate pore-permeability reservoir, feldspathic sandstone is mainly component,medium textural maturity. Maturity of component is low. Reservoir space is mainly made of residual intergranular porosity,and secondary dissolution porosity,intercrystaline pore. Based on textural characters of pore,reservoir is divided into 4 categories.
