| 摘 要： | 根据CO2驱油提高采收率机理,对低渗透油藏CO2驱油设计了正对行列注气、正对行列间隔注气、交错行列、行列注水4种注入方式,共6种开发方案,运用油藏数值模拟方法进行比较优选。结果表明：正对行列注气（油井150m井距、300m排距）的井网开发方案采出程度最高。运用该方案对油田进行注CO2开发具有较好的应用效果。

| Abstract: | The effects of four flooding patterns (parallel CO_2-injection, parallel interval CO_2-injection, parallel water-flooding, leaping parallel water-flooding) for low-permeable reservoir by the numerical stimulation are studied. The result shows that the recovery factor of parallel CO_2-injection(row spacing: 300 m, well spacing: 150 m) is more optimal than other patterns. The plan will enhance the recovery factor of low-permeable reservoir. |
