摘　　要：通过室内驱替实验研究了压力对空气泡沫渗流过程中的封堵能力和气泡大小的影响。结果表明:泡沫的封堵能力与压力成正比,压力为0.1MPa、5MPa和10MPa时,泡沫产生的阻力系数分别为48、58和70。气泡的直径与压力成反比,0.1MPa时,气泡平均直径约为7.38μm;压力为5MPa时,气泡平均直径约为5.46μm。压力为5MPa时,气泡与孔吼的匹配性比压力为0.1MPa时更好。This paper through the indoor flooding experiments to study the impact of pressure on the plugging capacity and size of the bubbles in the air foam percolation process. The re-sults showed that： the plugging capacity of foam is proportional to the pressure, the pressure is 0.1 MPa, 5 MPa and 10 MPa, the respectively resistance coefficient of foam is 48, 58 and 70. The diameter of the bubble is inversely proportional to the pressure. When the pressure is 0.1 MPa, the average diameter of bubbles is nearly 7.38 μm. When the pressure is 5 MPa, the average diameter of bubbles is nearly 5.46 μm. When the pressure is 5 MPa, the size of bubble is better match the pore than 0.1 MPa.
