Abstract: The volcanic rocks is development of the lower assemblage in Junggar Basin. Due to some objective factors influence such as deep burial depth, active and lasts long structural movement, many problems exits in the identification and interpretation of the complex faults system and deep volcanic rock body. Therefore, identification of faults using some approaches such as structure oriented filtering, eigenstructure combine with body curvature provide by GeoEast interpretation sub-system platform. Base on drilling data and 3D seismic, defining seismic reflection characteristics of differern volcanic lithology, established recognition model of volcanic facies in the study area. According to the multi-attribute pattern recognition and waveform clustering analysis provided by GeoEast, the lithology distribution of deep volcanic rock can be quickly and efficiently predicted, and favorable exploration targets in deep volcanic rocks are determined and optimized. Makes clear the volcanic target is development of the new layer series in the study area, which is an important exploration area to find large-scale oil and gas reservoirs.

Key words: interpretation sub-system, fault recognition, multi-attribute analysis, waveform clustering, volcanic prediction
