Abstract:
The inelastic spectrum-based carbon/oxygen spectral logging has been widely applied in the interpretation of residual oil saturation. The effects of traditional spectral processing methods for obtaining inelastic spectrum are influenced by salinity (including pore fluid salinity and borehole fluid salinity), clay content, porosity, etc. The interpretation accuracy thereof needs to be improved. In this paper, we proposed a new method for obtaining inelastic spectrum. To validate the new method and compare it with the traditional methods, the numerical simulation method (Monte Carlo) is used to simulate different formation models. The result shows that in addition to sandstone formation with clay, the new method improves the interpretation accuracy of oil saturation.
