The purpose of the present study is to evaluate the influence of CO_2 hydrate on the flow of liquid CO_2 when liquid CO_2 injected in a porous media. In order to reveal the influence of CO_2 hydrate, differential pressure was measured under each condition of CO_2 hydrate generated or not. As the results, in the case of CO_2 hydrate generated, it was identified that the value of the differential pressure became large compared with the case that CO_2 hydrate did not generate. It was suggested that flow resistance occurred due to choke of CO_2 hydrate in the porous media. And, friction factors were compared with the Ergun's equation proposed for single-phase flow in a porous media. The measured friction factor is larger than the value estimated from Ergun's equation.
