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