Abstract
Supplementing formation energy through water injection is the main way to develop old oil fields. However, formation non-homogeneity leads to the uncertainty of waterline advancement, which generates residual oil. In order to study the effect of water injection rate on the distribution of water-driven oil, we carried out water injection simulation experiments using the Tankou oilfield as an example. The oil saturation contour maps of several time points in the water-driven oil process were plotted by determining the trend of resistance value changes. We studied the drive path during the water-driven oil process, determined the location of residual oil distribution in the plane and longitudinal direction and analysed the reasons for residual oil generation. The study concludes that the optimal upper limit of the water injection rate in this area is 15 ml/min, which is converted to 24 m$^3$/day in the case of low injection and high recovery. In the case of high injection and low recovery, the daily water injection rate is 20 m$^3$ to verify the effect.
