柴达木盆地是我国七大含油气盆地之一，油气资源丰富，具备建立大型油气田的资源基础。受新生代强烈的喜马拉雅造山运动的影响，盆地内构造十分复杂，油气田生、储、盖组合的后期改造非常严重，使得勘探难度很大，“增储上产”曾一度面临严峻的形势。但近年来青海油田公司通过解放思想，在认真系统地分析柴达木盆地构造、沉积等油气地质条件及其特征的基础上，积极转变勘探思路，使得勘探工作连续取得突破，相继发现了昆北、英东２个亿吨级储量区，以及红柳泉、乌南、马北3个5000万吨级储量区，并在鄂博梁Ⅲ号和台南深层的天然气风险勘探中取得突破性进展。总结所取得的成功经验，归纳出5种指导思想和4条工作原则。这些思想和原则对柴达木盆地油气勘探的突破性进展和成功的增储上产起到了至关重要的作用。

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
