| 摘 要： | 强水敏油藏采用注水方式开发,存在注水困难,易对储层造成伤害等问题.而采用注气驱的方法开发水敏油藏,既能避免对储层造成伤害,同时又可取得明显的增产效果;另外采用CO2驱还可以减少温室气体的排放.细管实验表明,CO2和液化气+天然气段塞在地层条件都能与原油混相,可以获得较好的增产效果.长岩心实验的研究证明,水驱造成了岩心渗透率明显下降,岩心渗流能力伤害严重,注入水最终无法注入.而注气驱的增产效果远远好于水驱,同时可有效地保护储层. |

| Abstract: | The development of strong water sensitive oil reservoir has been a problem.There are a series of trouble in development of strong water sensitive oil reservoir by water flooding,such as difficult water injection and reservoir damage.Gas flooding in water sensitive oil reservoir has many advantages,on the one hand,it can increase oil production and protect the reservoir;on the other hand,the emission of greenhouse gas will be reduce.The result of slim-tube experiment shows that CO2 can be miscible with reser... |
