| 摘 要： | 文章利用钻井岩心、岩石薄片、测井、地震资料对塔里木盆地沙雅隆起北部三道桥气田潜山的地层格架、岩石岩相特征进行分析,并通过钻井岩心样品的锆石U-Pb年代学和野外地质露头地层对比研究,对这套潜山地层的时代进行了限定。研究结果表明三道桥潜山是一套厚度在700~800 m,浅变质的海相碎屑岩-碳酸盐岩沉积,3个碎屑锆石样品的最小谐和年龄为(1522±16)Ma,表明其沉积或成岩时代应不早于中元古代。该潜山是迄今为止塔里木盆地内获得工业油气的最古老的潜山。

| Abstract: | In this paper, the stratigraphic framework of the SDQ buried hill reservoir was built through using the drilling cores, loggings and seismic data of northern Shaya uplift in the Tarim Basin, and the rock lithofacies were analyzed through drilling cores and petrographic thin section. The stratigraphic age was determined through the U-Pb zircon geochronology of the drilling core samples, and was compared with the outcrops of the Kuruketag area in northeast Tarim Basin. The result shows that the SDQ buried hill is composed of some metamorphic marine sedimentary clastics and carbonate rocks, whose thickness is between 700 to 800 m. The minimum zircon concordia age is about 522 ±16 Ma from 3 clastics rock samples, which indicates that the deposition or diagenetic age should not be earlier than the middle Proterozoic. The SDQ buried hill reservoir is the oldest buried hill reported in the Tarim Basin. |
