Abstract:

Kuqa rejuvenated foreland basin is located along the northern margin of Tarim Basin.The characteristics of sedimentation and structures are of typical foreland basin.The hydrocarbon source rocks of Triassic Jurassic and reservoir cap rock assemblages developed well in the basin,and it is one of the important exploration areas.It has been demonstrated by study that:1.the matching of faulting time and hydrocarbon generation and expulsion phase is the key of the fault sealing ability;2.fault related fold is the most favorable structural trap;3.break through faults mainly destroied or reformed hydrocarbon reservoir;4.the lacking of conductive structures is the key of the defeat of deep exploration.Based on the relationship between structures and hydrocarbon accumulation,the northern anticline hydrocarbon accumulation zones and the northern anticline of Baicheng Yangxia syncline hydrocarbon accumulation zones are most favorable exploration targets at present.

Key words: rejuvenated foreland basin, foreland thrust belt, structure and hydrocarbon, exploration target, Kuqa
