Abstract: Recently two professors of Petroleum University in China, Mr. LUO Qun and PANG Xong-qi published an article indicated that according to their "fault control hydrocarbon theory" can chosen the most important exploration belts with great potential of oil and gas resources, forming huge hydrocarbon accumulations to realize a great breakthrough of petroleum exploration in Qaidam Basin. Although the article advanced some new view points and recognition, but some discussions are required such as: the fault control hydrocarbon theory is a successive research achievement of many petroleum geologists since 1960's not new idea from Luo in 1998;The middle-southern uplift as first significant exploration target for breakthrough major oil and gas discoveries has not enough petroleum geological evidence; the E-Bo-Liang (Ⅲ)-Yahu structural belt as a major breakthrough target requires revaluation. But the Yikeyawuru-Yahu structures and the westward Jiangshan-Dafengshan structures distributed in Northeast Slop Zone of Qaidam Basin, there are Middle and Upper Neogen sediments of lake and lake-shore facies, although the organic carbon content are low. But it reached gas generation level, the reservoir rocks relativeryly good. Yi-1 deep well discovered economical gas flow,all of these indicated this is a valuable region should be attracted our attention and further studies,may be discovers Neogen gas fields.

Key words: Qaidam Basin, fault control hydrocarbon, middle-southern uplift, oil and gas exploration, great breakthrough, discussion
