摘　　要：通过对新疆顺北油田B、C两井与塔河油田D井中-上奥陶统牙形刺的研究,从一间房组上部至恰尔巴克组下部识别出Dzikodus tablepointensis,Eoplacognathus suecicus,Pygodus serra和Pygodus anserinus-Yangtzeplacognathus jianyeensis等4个生物带。结合塔河油田A井的牙形刺研究,进而将两个地区的一间房组上部归为中奥陶统达瑞威尔阶中上部,恰尔巴克组归为上奥陶统桑比阶中下部,良里塔格组归为上奥陶统桑比阶中上部至凯迪阶下部,桑塔木组底部归为凯迪阶中部。顺北油田和塔河油田的中-上奥陶统牙形刺生物地层序列可以与塔里木盆地的区域标准牙形刺生物带进行对比。Four conodont biozones,including the Dzikodus tablepointensis,Eoplacognathus suecicus,Pygodus serra and Pygodus anserinus-Yangtzeplacognathus jianyeensis biozones were recognized through the study of the Middle to Upper Ordovician conodonts from the upper Yijianfang Formation to the lower Qiaerbake Formation of the wells B and C in the Shunbei Oilfield and Well D in the Tahe Oilfield,Xinjiang.In the studied area,the upper Yijianfang Formation corresponds to the middle to upper Darriwilian,the Qiaerbake Formation to the lower to middle Sandbian,the Lianglitage Formation to the middle to upper Sandbian to lower Katian,and the Sangtamu Formation to the middle Katian.The Middle to Upper Ordovician conodont biostratigraphy of the Shunbei and Tahe oilfields can be correlated with local conodont biozonation of the Tarim Basin.
