| 摘 要： | 渗吸作用是油藏基质原油开采的关键,CO2溶入地层水将对渗吸作用产生影响.进行了亲水岩心的润湿性转变实验,测试了亲油岩心在碳酸水浸泡前后润湿接触角的变化,比较了亲油性岩心在碳酸水和盐水中的渗吸效果.研究结果表明,模拟油浸泡法使得岩心润湿性变为油湿性;油湿性岩心经过碳酸水浸泡可使润湿性向水湿性转变;碳酸水有利于改善油湿性岩心渗吸效果,促进渗吸过程的进行. |

| Abstract: | Imbibition action plays an important role in the production of matrix oil.CO2 dissoluting into formation will produce an effect on the rock imbibition.The relationship between contact angle of hydrophilic cores and the time when they are immersed in simulation oil are tested.The contact angle variation of oil wet cores is tested before and after they are immersed in carbonate water,and their imbibition effects in carbonate water and salt water are compared.The results show that,the immersion in simulation o... |
