| 摘 要： | 国内高凝油一般含蜡量高、凝固点高，凝固点与地层温度接近的高凝油易产生冷伤害，开采难度大。针对二氧化碳吞吐开采高凝油过程中，二氧化碳对高凝油的粘度、流动特性、凝固点的变化开展实验研究，研究表明二氧化碳溶解后高凝油粘度大幅下降、凝固点大大降低，流动性得到明显改善，二氧化碳吞吐开采高凝油可改善开发效果。 |
| 关 键 词： | 二氧化碳 含蜡量 凝固点 地层 温度 注气开发工艺 渗透率 |

| Abstract: | The paraffin content and solidification point of high pour-point oil are high in China.If the solidification point of high pour-point oil is near formation temperature,its production will be difficult.The paper research the influence of CO 2 on the viscosity,flow behavior,and solidification point of high pour-point oil.The research results show that viscosity and solidification point of high pour-point oil are reduced after CO 2 solution ,and its flow behavior is also improved.CO 2 huff and puff technology can improve the development effect of high pour-point oil. |
| Keywords: | high pour-point oil gas injection CO 2 physical property of crude oil |
