Abstract:

 There is a large amount of remaining oil in reservoir after water flooding. How to recover remaining oil efficiently and economically is a main task in old oilfields. The remaining oil in reservoirs is by low sweep efficiency and low displacement efficiency. The low displacement efficiency of reservoirs is usually caused by residual oil in water flooded area. The residual oil is formed by Jamin effect of capillary pressure. Higher injection rate of water may overcome Jamin effect and increase the displacement efficiency of oil, however it wastes water and is not allowed by common engineering conditions. Long term water flooding can also increase the displacement efficiency of oil, but it wastes water too and has not economic benefit. Buoyance drive can increase the displacement efficiency of oil by elimination of Jamin effect, and even the displacement efficiency of oil can be raised to the final limit of 100%. For middle or high permeability reservoirs, periodical injection of water can be used to increase the displacement efficiency of oil by buoyance drive and cut down the cost of water injection for higher economic profit of oilfield development.
