Abstract: Wuerhe-Xiazijie area is divided into nine structural units, and has nine sedimentary facies types and three sedimentary systems. The different structural zones allowed to developing different sedimentary systems. The growth fault caused the differences in sedimentary thickness of isochron strata and in sedimentary system in two sides of the fault. The fault's strike controlled the distribution directions of the sedimentary systems, and the step thrust faults formed multiple steep fan-delta. Wuerhe anticline fan-delta front (middle alluvial fan), Wuerhe-Xiazijie-Karameli thrust belt fan-delta plain (root alluvial fan), Xiazijie-Hongqiba bruchfalten zone fan-delta plain (root alluvial fan) tectonic-lithofacies zones are favorable locations for hydrocarbon accumulation.

Key words: Junggar basin, Wuerhe, Xiazijie, structural system, tectonic-lithofacies zone, hydrocarbon accumulation
