Simulation Analysis Of Drag-Reduction Effects Of Aqueous-Base Foam On Heavy Oil Flow With Different Injecting Rates

Aqueous-base foam injected into oil flow can reduce the flowing drag and retrench transportation energy. While how much amount of injected foam and injecting rate remain unresolved. Based on computational fluid dynamics, numerical simulation method was present in this paper to analysis the drag-reduction effects of aqueous-base foam on heavy oil flow with different injecting rates. The thickness of boundary layer is different for diverse foam injecting rate. Low injecting rate may lead to thin foam boundary layer, but not necessarily the worst case. Suitable rate ratio of foam and oil should be considered in practical operation.
