| 摘 要： | 针对CO2在稠油开采过程中所起的作用,在室内对稠油CO2混相体系性质进行了研究。结果表明,在相同的温度下,随着压力的增高,原油对CO2的溶解度增大;同样压力的情况下,温度越高CO2的溶解度减小;CO2在油水系统油中所溶解的比例,随温度、压力的升高而减小,随含水量增加而下降;在温度一定的条件下,原油的黏度降低幅度随着压力增加、CO2溶解度增大而增大。

| Abstract: | In view of the effect that the CO2palys in the heavy oil recovery,the miscible phase system complexion of heavy oil and CO2has been researched ineterior.The results show that,in the same temperature,with the increasing pressure,the CO2solubility in crude oil broaden;under the same pressure,the higer temperature,the lower CO2 solubility ;the CO2 solution proportion in oil water system,with the addition of temperature and pressure decreases,in the wake of increaseing of moisture content declines;under definit... |
