泡沫薄膜液在变径管内的流变学特性
Foam lamellae flow rheology in converging-diverging tubes
摘要
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.Nondimensional parameters of △pD/δ and (3μ U/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.关键词
