Abstract

The effects of four flooding patterns（parallel CO₂-injection, parallel interval CO₂-injection, parallel waterflooding, leaping parallel water-flooding） for low-permeable reservoir by the numerical stimulation are studied. The result shows that the recovery factor of parallel CO₂-injection（rowspacing: 300 m, well spacing: 150 m） is more optimal than other patterns. The plan will enhance the recovery factor of low-permeable reservoir.
