| 摘 要： | 自１９８４年９月地矿部在塔北沙参２井奥陶系油气勘探首次取得重大突破后，又在塔北、塔中、塔西南相继获得发现或突破，形成了第一轮以奥陶系为重点的油气勘探热潮。虽在１９９１～１９９５年由于认识上的影响一度出现油气勘探低谷，但从１９９６年开始又迎来了新一轮塔里木盆地奥陶系油气勘探的新高潮。多年油气勘探实践和研究表明，塔里木盆地奥陶系油气资源潜力相当巨大，具备形成大油气田的条件，是塔里木盆地今后寻找大油气田的主要层位之一。

| Abstract: | In September 1984,the well Sha-2 drilled by the Ministry of Geology and Mineral Resources in the North Tarim basin flowed natural oil gas from the Ordovician dolomites,which makes the first significant breakthrough of the oil explorations in Tarim Basin.After that ,CNSPC and CNPC have many discoveries of oil gas fields in the Central,Northern and West southern Tarim basin,which resulted in the highlight exploration and development of oil gas from the Ordovician .But from 1991 to 1995,the exploration presented low tide because of recognizing in exploration.In 1996,the Ordovician exploration became new and important high tide ,a lot of researches indicates that Ordovician has a great potential to form a big oil gas reservoir ,it is one of the most promising horizons for oil gas prospecting in Tarim region |
