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。文章针对二氧化碳吞吐开采高凝油过程中对高凝油的粘度、流动特性、凝固点的变化进行了实验研究。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。
Generally, high solidification point oil possesses the property of high wax content,high solidification point in China,of which it's solidification point approaches to the formation temperature is easy to cause cold damage and difficult to be developed,this paper carried out an experimental research on the changing of CO 2 to the viscosity , fluidity , solidification point of high pour solidification oil in the process of which be developed by huff and puff with CO 2, the result suggests that after CO 2 dissoloved, the viscosity and solidification point of high solidification point oil decreases a large , the fluidity is improved obviously , and the production effects of high solidification point oil can be improved by huff and puff with CO 2.
