Heavy Oil Reservoir

Mengulin sandstone reservoir in Huabei oilfield is low- temperature heavy oil reservoir. Recently, it is at later stage of waterflooding development. The producing degree of water flooding is poor, and it is difficult to keep yield stable. To improve oilfield development effect, according to the characteristics of reservoir geology, microbial enhanced oil recovery to improve oil displacement efficiency is researched. 2 microbial strains suitable for the reservoir conditions were screened indoor. The growth characteristics of strains, compatibility and function mechanism with crude oil were studied. Results show that the screened strains have very strong ability to utilize petroleum hydrocarbon to grow and metabolize, can achieve the purpose of reducing oil viscosity, and can also produce biological molecules with high surface activity to reduce the oil-water interfacial tension. 9 oil wells had been chosen to carry on the pilot test of microbial stimulation, of which 7 wells became effective with better experiment results. The measures effective rate is 77.8%, the increased oil is 1,093.5 tons and the valid is up to 190 days.

Displacement Adjustment Method

According to the characters of conventional heavy oil reservoir, liquid and exploitation progress, displacement adjustment method was applied to reduce degression and enhance recovery. The experiment results showed the gel time could be controlled and the strength could be adjusted. The flooding oil rate was more 14.3％ than water flooding in the lab. The pilot test showed that the test effect of moveable gel flooding was significantly good, the accumulated incremental oil production of 6 well groups is 54756t, input-output ratio is 1: 4.1, which shows satisfactory effects in improving the water flooding effect in this conventional heavy oil reservoirs.
