1.Results have shown that increase of fluid volume can produce more oil than fixed liquid volume during polymer flooding, enhance oil recovery 7. 25% ~ 8. 77% , regardless of in monolayer or aeolotropic multiplayer formation.
3.The results of core experiments show that the mixture fermentation liquid of these two bacteria can increase the recovery factor of the crude oil after polymer flooding by 12.26%.
4.There are many factors affecting production dynamic of horizontal well,such as oil reservoir physical property and liquid character that are static factors,but there are not any studies about production dynamic of horizontal well affected by water flooding.
5.The flooding device of submarine accumulator battery, which consists of electromagnetic water level sensor, isolating switch, single chip controller and alarm system, is researched and designed. The liquid surface error of accumulator battery is less than 5mm.
6.With the dosage of the newly formulated oil/waterseparation agent at 20mg/L, polymer flooding produced liquid can undergo well phase separation after Ih 45C thermal settling, resulting in only 2.88% water in the oil phase and 651.1 mg/L oil in the water phase.
