At the same time, the features and hydrocarbon potential of the rejuvenated foreland basins around intracontinental orogens in Mid-West China are discussed.

The paper presents firstly the features of the hydrocarbon-expulsion of the major source rocks in the Kuqa rejuvenated foreland basin, northwestern China.

Kuqa rejuvenated foreland basin is located along the northern margin of Tarim Basin.

The subsurface structures of the Kuqa rejuvenated foreland basin are really complex, so a correct interpretation of them is the key for understanding the genesis of the basin and hydrocarbon traps.

Transporting conditions of faults required in formation of large and medium gas fields with high efficiency in foreland basin;

Different origins of natural gas in secondary gas pool in Western Sichuan foreland basin;

Overpressure compartment sealed by faults in Kuqa foreland basin;

Based on forland basins evolution,tectonic features,sedimental model,thermal process,reform process and model recovery,the paper analyzes forland basins theories and pays more attention to geological process,evolutional development and sedimental model.
