The main objective of the present study was to clarify two-phase flow characteristics of a cleat (fracture) network in coal, for applications to the CO2-ECBM/S. Two-phase flow experiments and model simulations on mated fractures revealed relative permeability curves of fractures, which were entirely different from existing models, suggesting necessity of further studies on two-phase flows through fractures.

本研究的主要目的是阐明煤中割理（裂隙）网络的两相流动特性，以应用于CO2-ECBM/S。通过裂缝两相流实验和模型模拟，得到了与现有模型完全不同的裂缝相对渗透率曲线，表明有必要对裂缝两相流进行进一步研究。
