Characteristics of oil microbes and Microbial Degradation on Heavy Oil
Degradation of oil is a most important part of the MEOR. This procedure can reduce the oils viscidity and freezing point and improve the oils fluxion in- situ. The authors first discuss bacterias capability of producing gas and the DNA trial strip. The authors also discuss the encouraging results of the microbial degradation on the heavy oils gathered from several big oil fields in China. The results show that the bacteria can efficiently improve the property of the oils. The gum & asphalt content of the oils are lowered at above 9％ and their structure is also changed a bit. The ΣnC<21->/ΣnC<22+> of the oils are enhanced through the microbial treatments and the shapes of oils in solution are changed greatly. The oils viscidity and freezing point are reduced about 15％ and 20％ respectively.
