摘要: 针对辽河油田冷东-雷家地区沙河街组砾质扇三角洲储层的特点,在对储层进行宏观作均质性和微观孔隙结构研究的基础上,求取了反映储层特征的13项参数,应用主成分分析方法,对储层进行了分类评价.评价结果表明;各类储层的分布规律性强,为下一步编制开发方案,合理划分开发层系奠定了可靠的地质基础.进一步证明主成分分析方法在砾岩储层评价中的实用价值及可行性.

Abstract: Aiming at studying thereservoir characteristic of gravel fan-delta of Shahejie group inLengdong-Leijia region,Liaohe oil field,13 types of parameters were aquisited to representthe reservoir characteristic on the basis of investigating reservoir's macroscopic heterogeneityand micropore structure,Then classification evaluation was carried out with the method ofprincipal component analysis,The results show that the distribution of all types of reservoiris farely regular,which lays a reliable geological foundation for drawing up programme andreasonably differenciating layer system for field developement in the future.Moreover,thepractical value and the feasibility of principal component analysis was furtherly verified.
