Abstract
Aiming at conventional heavy oil reservoir, 3-D dimensional cross-section model was employed to study thermal water flooding or water-steam alternative injection after steam flooding in anti-rhythm reservoir, positive rhythm reservoir and composite rhythm reservoir. The results show that steam trended to flow on the top of reservoir due to over lap of injection steam. Steam channeling is more easily generated in anti-rhythm reservoir than in positive rhythm reservoir. Thermal water flooding and water-steam alternative injection after steam flooding could carry remaining heat to migrate into the bottom of reservoir, so amount of heavy oil in reservoir can be recovered. The recovery efficiency of water-steam alternative injection is obviously higher than thermal water flooding and water cut decreased largely during water-steam alternative injection.关键词
