摘要
Oriente盆地白垩系Napo组UT层的海绿石砂岩储层是近几年发现的岩性油藏。为解决海绿石在储层中的作用及海绿石的含量对储层质量的影响,研究海绿砂岩石储层的特征。以岩石薄片、铸体薄片资料为基础,分析了海绿石储层矿物成分、岩石学特征、物性特征、孔隙结构。通过测井解释资料分析了海绿石在平面上及纵向上对储层孔隙度、渗透率的影响,研究海绿石油藏特征。应用灰色关联法计算储层评价过程中各项参数的权系数,评价了海绿石砂岩储层综合指数,分析优势储层,绘制平面质量展布图,为后期开发海绿石油藏提供了地质基础,也为此类储层的综合评价提供了借鉴意义。
Oriente basin in cretaceous Napo UT layer set of glauconite sandstone reservoir is found as the lithologic reservoir in recent years. In order to solve the role of glauconite in reservoir and the content of glaueonite influence on reservoir quality, as well as the study of the characteristics of green sand rock reservoir, based on the data of rock thin section, casting thin sections, this paper analyzes the glauconite mineral composition, petrological characteristics, reservoir physical characteristics and pore structure. Glauconite was analyzed by using well logging interpretation data on the plane and longitudinal impact on reservoir porosity, and permeability, the green sea oil characteristics. The gray relational method is used to calculate the weight coefficient of each parameter in the reservoir evaluation process. The comprehensive index of the glaueonite sandstone reservoir is evaluated; the favorable reservoir is analyzed, and the plane quality map is drawn to provide the geological support. And it also provides reference for the comprehensive evaluation of such reservoirs.
