| 摘 要： | 国内外研究表明CO2驱是低渗透油田开发的有效方法之一,针对低渗透油藏自然产能低、地层能量不足、地层压力下降快等引起采收率低的现状,在CO2驱油机理分析的基础上,通过数值模拟方法对CO2驱注入参数进行研究,结果表明CO2驱具有良好的开发效果,对后期的CO2驱推广应用具有指导意义。

| Abstract: | Studies at home and abroad show that CO2 flooding is one of effective methods of low-permeability oil field.We study the CO2 flooding injection parameters through numerical simulation,aiming at the status of low recovery ratio caused by low natural capacity of low-permeability reservoirs,insufficient formation energy,fast formation pressure drop,based on analyzing CO2 flooding mechanism,the results show that CO2 flooding has good development effect,which has guiding significance for the promotion and application of later CO2 flooding. |
