The Application of Analysis of Variance Method to Optimize Injection Parameters of Polymer Flooding in Sub-Layers
Combining with static information of injection wells and using effective thickness, number of layers greater than 1 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.
