Based on outcrop, drilling, well logging, seismic, testing and analytical data, it is suggested that the Kunbei thrust beh is a Cenozoic palaeotectonic belt developing on a palaeogeomorphic uplift background and controlled by piedmont faults of the Kunlun Mountains,the Kunbei I fault and Kunbeil] fault, where traps including palaeogeomorphic uplift, formation-lithology and anticline ones have formed various oil-gas reservoirs. Key factors controlling these hydrocarbon accumulations include early paleogeomorphic uplift, good fault-unconformity carrier system, regional stable fine-grained caprock, plenty of distal source supply and long-term oil and gas filling caused by continuous fault activities, thus a large scale of reservoirs is formed. The discovery of the Kunbei oil field has developed the oil gas exploration domain of the Qaidam Basin and deepened our understanding on hydrocarbon accumulations.
