纳米颗粒对CO_2存储作用的实验研究

Nanoparticle evaluation method on CO_2 storage experiment

化石能源的消费导致大量CO_2排放到大气中,为降低对环境的影响,实施CO_2地下埋存被认为是当前最有效和最具可行性的方式。实验借助先进的CT扫描技术,研究岩心在被纳米颗粒溶液饱和后,CO_2在其中的流态特征及饱和度变化。实验表明:CO_2在被纳米颗粒溶液饱和的岩心中波及面积大,指进速度慢,说明岩心在被纳米颗粒溶液饱和后,存储CO_2的能力大大增强,存储效果更明显。

Fossil energy consumption leads to large amount ol CO2 emissions into the atmosphere, in order to reduce CO2,s impact on the environment,the CO2 underground storage is considered to be the most effective and leasible method. 1 n this experiment,with the advanced CT scanning technology,the flow characteristics and saturation changes ol CO2 in the core were studied alter the core saturated by nanoparticle solution. Experimental results show that CO2 drainages larger area and less finger flow in the core by ellecting ol nanoparticles. The study indicates that nanoparticle improves CO2 storage ca-pacity in sand lormation and storage ellect is more obvious.
