Studies on Viscous Fingering Phenomenon in Displacing Oil Solution by Aqueous PAA Solution(Ⅰ)
Abstract:
An improved model is described to simulate the viscous fingering phenomenon occurred in oil recovery.The random complicated branch-sheeped pattern has been treated on the principles of fractal geometry and the influences of the viscocities of the oil phase and water phase,displacing flow rate, spacing between plate glasses and temperature on the viscous fingering phenomenon have been investigated.The results indicate that the mobility ratio of the aqueous polyacrylamide (PAA) solution to oil is the key to controll the viscous fingering phenomenon, and when the mobility ratio is equal to one or less, the phenomenon occurs little.
