Abstract: With the progress of oil-gas exploration in Junggar basin, the structural traps to be explored become less and less. The explorative targets have been converted from structural traps into lithologic and stratigraphic non-structural traps. This paper presents the composite interpretation and analysis of seismic multi-attributes of the lithologic (oil-bearing) sands in 201 Well Area in Karamay field, in terms of waveform and mutative area, well restrictive inverse and root-mean-square amplitude, etc., and good geologic results are gained.

Key words: 3D seismic attribute, lithology, trap, identification
