Identification of Subtle Oil/Gas Reservoir in Junggar Basin of

This article utilizes the spectral factorization technique, full 3-D visualization, and full 3-D data volume interpretation technique in the 3-D work zones of C43 well, G8 well, and SN4 well, situated in the east part, northwest margin, and “hinterland” of the Junggar Basin, respectively, of West China. Also, this article has effectively predicted the spatial distribution of channels and the lithologic body of reservoir and identified the boundary and size of the lithologic trap. The scale of lithologic oil/gas reservoir in SN31 well has been discovered after the successful application of these three techniques, which have provided a new idea for the exploration of subtle oil/gas reservoirs in Junggar Basin. The considerable importance of selecting appropriate approaches needs to be noticed when the study of subtle oil/gas reservoir is conducted; this approach serves as a vital part of achieving success in exploration.
