Abstract: Based on the low permeability and high salinity oil reservoirs of Jurassic, this paper summarizes the
experiences and lessons of polymer flooding experiments in recent years. According to the present technology in
weak polymer gel flooding at home and abroad, and based on the geologic reservoir features and current status of
exploitation, a weak polymer gel flooding system which meet the situation of low permeability and high salinity oil
reservoir of Jurassic is developed, and the system performes well in the field experiment. The results showed that
weak polymer gel flooding system is suitable for low permeability and high salinity oil reservoirs; it can slow down
the descending, reduce the water ratio and enhanced oil recovery.

Key words: high salinity, low permeability, weak polymer gels, decrease, enhanced oil recovery
