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

摘要： 石油大学罗群、庞雄奇教授运用“断裂控烃理论”,论述了实现柴达木盆地油气勘探中的大突破方向,提出了一些新的观点和认识。但文章中也存在一些值得商榷之处,如断裂控烃理论应该是20世纪 60年代以来众多专家研究成果的继承和发展,而不是1998年新提出来的;中南隆起做为大突破方向,地质论据不足;鄂博梁Ⅲ号和鸭湖构造带能否作为柴达木盆地油气勘探重大突破目标尚须重新评价。但罗文提出的包括依克雅乌汝、鸭湖等构造范围内的柴达木盆地东北斜坡带,上第三系中上部为一套浅湖、滨湖相沉积,有机质丰度虽低,但大部达到了盆地生气层标准,储层相对较好,伊深1井已发现低产工业气流,这是一个值得重视和进一步研究的层系,配合采用平衡钻井技术,有可能获得上第三系的气藏。
