Grey Correlation Analysis of Influence Factors on Daily Water-Injection Rate of Each Well Group

Abstract:

In order to determine the influence factors on daily water-injection rate of each well group, we collected actual production performance data of 65 well groups in eastern Nan 8 area, Daqing oilfield and statistically analyzed the dynamic and static parameters such as effective thickness, connected thickness, connected direction number, oil saturation, water cut and water cut rising velocity. Then we calculated the grey correlation degree between these 6 factors and daily water-injection rate by means of grey correlation analysis method. Results of the study show that, the major influence factors on daily water-injection rate are (from high degree to low degree) water cut rising velocity, oil saturation, water cut, connected direction number, effective thickness and connected thickness. This method can serve as guide for reasonable daily water-injection rate determination.
