Abstract
Due to the difficulty in the exploitation of heavy oil, chemical flooding as a technology to enhance oil recovery has received extensive attention from the petroleum industry. In view of actual engineering needs, taking Jin 8 block as an example, the single variable method is used to optimize the injection-production parameters affecting heavy oil chemical combination flooding. The results show that the injection concentration is 0.6%, the slug ratio is 3:2, and the injection section. When the plug volume is 0.35PV, the development effect is better, which can provide theoretical guidance for the actual production of heavy oil reservoirs.
