Application of Seismic Multi-Attributes to Identification of Non-Structural Traps——An example from 201 Well Area in Karamay field

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.
