Abstract:

The analysis of the production data of Jinglou Oilfield of Henan and one of its pilot-areas, Opilot,reveals the recovery law of cyclic steam simulation and steam flooding in thin thickness heavy oil reservoir: While the vertical displacement is efficient and the recovery rate and percentage are high, the oil production rate per well, cyclic oil production and oil-steam ration are low, and oil production declines fast.

Key words: steam flooding, cyclic steam, thin thickness heavy oil reservoirs, heavy oil recovery law
