Abstract

As traditional AVOtechniques can not be used to visually evaluate the hydrocarbon potential of the reservoir, so the extracted AVO attributes are not well in accord with the gas-bearing properties of the actual wells. This paper proposed AVO fluid inversion to analyze the gas-bearing properties in northeastern Sichuan. This technology was successfully applied in the fourth member of Xujiahe Formation in one area of northeastern Sichuan. The result was consistent with case of actual wells, and good results have been achieved, which affords a favorable evidence for reservoir prediction in this area.
