Abstract: Light oil reservoirs with high productivity are discovered in Shawan Formation of Well Pai-2 in Chepaizi area of Junggar Basin. They have "bright spot" seismic characteristics due to the shallow burial depth, light density, large mudstone segmentation, good physical properties of reservoir, low speed of reservoir and its big difference with wave impedance of surrounding rock. The reservoir is identified using such approaches as composite seismogram calibration, forward modeling, analysis of seismic properties, and inversion, and good results are obtained.

Key words: bright spot, composite seismogram calibration, property, identification, Chepaizi area
