ABSTRACT
Based on reservoir condition and fluid characteristics, the oil-degrading bacterial strain NX-2 was screened from Ma-2 fault block of Huabei oil field. Bacterial metabolism and the capability of improving oil property were evaluated on oxygen-deficient condition. At 87℃ which reservoir temperature is, artificial homogeneous core displacement experiment indicated the enhanced oil recovery of microbe was 7.1% higher than that of waterflooding. In experiment on individual well Ma-410, additional oil production of 669 tons was gained, and decreased water production of this trial well reached more than 3000 tons. These results demonstrated NX-2 could adapt to stratum conditions, enhance oil recovery and improve oil property as well.
