摘要
首先利用统计分析中的聚类分析方法,结合水井静态资料,以有效厚度、大于1米层数及大于1米3～4向连通厚度比例作为评价指标,对大庆油田萨中开发区北一二排西、东区块的注入井进行分类;再以单位厚度累积增油量作为评价依据,利用单因变量双因素方差分析方法分别对已分类的不同类型注入井的注入速度和注入浓度进行优选.
Combining with static information of injection wells and using effective thickness, number of layers greater than i meter and ratio of 3 to 4 connected thickness greater than 1 meter as evaluation index, this paper use cluster analysis method to category injection wells of west and east blocks in north first and second row of Sazhong development area in Daqing oilfield. Then, with evaluation of accumulated increased oil per unit thickness, using single dependent variable two-factor variance analysis method to optimize injection rate and injection concentration of injection well groups which have been classified into different types.
