| 摘 要： | 对塔里枯木要盆地西部巴楚断隆，阿瓦提凹陷古生代产出的牙形刺化石进行了研究。建立了５个牙形刺化石组合带，讨论了其地史分布及其地质时代，牙形刺化石颜色指标研究表明，巴楚断隆区古生代地层中的烃源岩正处在热演化的成熟期，寻找古生代油气藏应成为该构造带今后勘探的重点；阿瓦提凹陷古生代石炭系的烃源岩已经处于热演化的高成熟期，寻找古生代凝析油气藏应成为本区今后勘探的重点。

| Abstract: | Study is made on palaeozoic conodont fossil from Bachu Uplift and Awati Depression. 5 conodont fossil assemblage zones are identified. And their geological history and geological eras are discussed. Research on color index of conodont fossil shows that hydrocarbon source rocks in palaeozoic formation in Bachu Uplift Area are in mature phase of thermal evolution. Future exploration in this structural belt should center on looking for palaezoic hydrocarbon reservoirs. In Awati Depression, hydrocarbon source rocks of carboniferous system in palaeozoic era are in highly mature phase of thermal evolution. Exploration in this area should focus on looking for palaeozoic condensate hydrocarbon reservoirs. |
