Abstract:

Given consideration to the situation of fast descending of production and the recovery factor in Tahe oilfield, the water injection and production were experimentalized on the spot. The experiment separated oil and water, supplied the reservoir energy, made speed the oil flow into well bore, added the lift energy, and enhanced the production and the recovery factor of the reservoir by using the principle of gravitative differentiation. The result of onthespot experiment in well T707 indicates that water injection and production are feasible and available. By applying the measure to 32 oil wells, the increment of oil production was 13 to 285 t and the increment in period was 55 to 3,105 t. Therefore, the technology is a new effective production mode in carbonated reservoir.

Key words: carbonate reservoir, water injection and production, recovery factor, production mode, numerical simulation
