| 摘 要： | 针对泡沫流体在储层介质内的流动特点，对泡沫薄膜液在变径管内的流变学特性进行实验研究。基于两相流动假设，利用量纲分析法确定量纲1参数ΔpD/δ及（3μU/σ）2/3。通过CO2及N2泡沫的实验结果发现泡沫薄膜液在变径管内流动时需克服启动压力，量纲1参数间呈明显的线性关系，而且N2泡沫与CO2泡沫相比具有更大的流动阻力。与直管相比，泡沫薄膜液在变径管内具有更大的流动压差。实验结果表明，对于揭示泡沫液在多孔介质中的流动机理，Herschel-Bulkley模型优于幂律模型。

| Abstract: | Corresponding to the foam flow characteristics in the reservoir media, experimental studies were carried out concerning CO2 and N2 foam lamellae flow rheology in a converging-diverging tube. Non-dimensional parameters of ΔpD/δ and (3μU/σ)2/3 were determined based on two-phase assumption of the foam fluid. Clear linear relationships between the two non-dimensional parameters were observed for both CO2 and N2 foam lamellae flow with various threshold values, which indicates startup pressure is needed to initiate the foam flow. Compared to CO2 foam, N2 foam shows higher flow resistance. While compared to the case in a straight tube, the lamellae flow in the tube with varying diameters has higher pressure drops. It is concluded instead of the power law model, the Herschel-Bulkley type rheology model could be more suitable for describing foam flow mechanism in porous media. |
