本研究的目的是研究二氧化碳水合物对注入多孔介质中的液态二氧化碳流动的影响。为了明确CO2水合物的影响，在CO2水合物生成和不生成的情况下测量压差和温度。结果，在水合物生成的情况下，证实测试部分的温度升高。并且可以看出，与没有产生的情况相比，压差变大。这表明流动阻力是由于多孔介质中二氧化碳水合物的阻塞而产生的。摩擦系数还与针对多孔介质中单相流提出的额尔古纳方程进行了比较。测量的摩擦因数大于根据额尔古纳方程估算的摩擦因数。
The purpose of the present study is to investigate the influence of CO2hydrate on the flow of liquid CO2injected in the porous media. In order to clarify the influence of CO2hydrate, differential pressure and temperature are measured under both condition of CO2hydrate generated and not generated. As the results, in the case of the hydrate generation, it is confirmed that temperature of the test section rise. And it is identified that the differential pressure become large compared with the case of not generated. It is suggested that flow resistance arises due to choking of CO2hydrate in the porous media. Friction factor is also compared with the Ergun’s equation which is proposed for single-phase flow in a porous media. The measured friction factor is larger than that estimated from Ergun’s equation.
