Determination of Residual Oil Saturation Distributions in Gao Taizi Area Using C/O Spectral Logs and Multiwell Interpretations.

C/O spectral log is an effective logging method for determining current residual oil saturation. In order to exactly know the residual oil saturation distribution in the fine geological researches in oilfields,we proposed a method that combines C/O spectral log with multi well interpretation to determine residual oil saturation distribution. More than 270 wells in Gao Taizi area in the 5th Production Factory of Daqing Oilfield have been interpreted, and their relative 3 D geologic models have been established, too. By combining C/O data obtained from the area, the residual oil distribution and got satisfactory results have been acquired.All these allow helping the production factory in its fine geological researches, adjusting injection production ratio and increasing recovery efficiency.
