Abstract EN
Oil viscosity was studied as an important factor for alkaline flooding based on the mechanism of “water drops” flow.
Alkaline flooding for two oil samples with different viscosities but similar acid numbers was compared.
Besides, series flooding tests for the same oil sample were conducted at different temperatures and permeabilities.
The results of flooding tests indicated that a high tertiary oil recovery could be achieved only in the low-permeability (approximately 500 mD) sandpacks for the low-viscosity heavy oil (Zhuangxi, 390 mPa·s); however, the high-viscosity heavy oil (Chenzhuang, 3450 mPa·s) performed well in both the low- and medium-permeability (approximately 1000 mD) sandpacks.
In addition, the results of flooding tests for the same oil at different temperatures also indicated that the oil viscosity put a similar effect on alkaline flooding.
Therefore, oil with a high-viscosity is favorable for alkaline flooding.
The microscopic flooding test indicated that the water drops produced during alkaline flooding for oils with different viscosities differed significantly in their sizes, which might influence the flow behaviors and therefore the sweep efficiencies of alkaline fluids.
This study provides an evidence for the feasibility of the development of high-viscosity heavy oil using alkaline flooding.
