Abstract

Qaidam basin,which is the seventh-largest petroliferous basins in China,is rich in oil and gas resources.Therefore,the basin possesses the conditions to be a large-scale oil and gas field.However,the strong Cenozoic Himalayan orogeny resulted in the complex structure of Qaidam basin.The source-reservoir-cap assemblage of the oil and gas field has been reformed intensively.And later reformations make the exploration become more difficult.For the petroleum enterprise,once faced a harsher circumstance to increase reserve and production.However,in recent years with the great support of the joint-stock company leadership,Qinghai Oilfield Company continues to emancipate the mind.In terms of carefully and systematic analysis of the structure,deposition and petroleum geological conditions of Qaidam basin,explorationists changing the old exploration thoughts positively,and the exploration work obtains continuous breakthroughs.Two oil fields with 100 million ton reserves (Kunbei,Yingdong) and three oil fields with 50 million ton reserves (Hongliuquan,Wunan and Mabei) were sequentially discovered by Qinghai Oilfield Company.Natural gas risk exploration in deep zone of Eboliang Ⅲ and Tainan reserves fields has also gains a major breakthrough progress.According to summarize the successful experience,we can sum up five guiding ideologies and four working principles.These ideas and principles play very important roles in making exploration work get breakthrough progress and successfully increasing reserves and production of Qaidam basin

Key words： Qaidam basin; Guiding ideology; Exploration work; Breakthrough
