Abstract: Based on composite analyses of seismic, drilling, well logging and outcrop data, together with interwell and log-seismic correlations, four third-scale sequences and eight system tracts are identified, firstly establishing the sequence stratigraphy correlation framework of Jurassic in Hong-Che fault zone. This will take an important part to search for lithologic subtle reservoirs in northwestern margin of Jungger basin.

Key words: Junggar basin, Hong-Che fault zone, Cretaceous, sequence stratigraphic classification, system tract, lithologic trap
