Abstract：The Heshituoluogai Basin is an Early Mesozoic basin in the large thrust fold belt in northwest Junggar, Xinjiang. Applying basin dynamics theory, basin-range coupling idea and balanced cross section technique, this paper shows the complete structural interpretation and resumes the tectonic evolution of the basin area. The controls and influences of the tectonic evolution on the migration and accumulation of oil and gas in the area are also analyzed and discussed. On this basis, it is concluded that: 1) The tectonic evolution in the area of Heshituoluogai Basin, closely related to the northwest Junggar Basin and Hala,alate Mountain, can be divided into prototype stage (C-T), major development stage (J-K) and reconstruction stage (E-Q); 2) The Heshituoluogai basin, with fairly good hydrocarbon source rock, many reservoir-seal assemblages, different types of traps, faults and regional unconformities, has good conditions for oil and gas migration; 3) The western basin should be the key target, where comprehensive studies on Jurassic low-mature gas and coal-formed gas could be strengthen.
