| 摘 要： | 本文对坪北油田长62油层组3种主要类型的短期基准面旋回结构特征及分布进行了详细描述。在高分辨率层序地层划分对比的基础上，建立了长62油层组高分辨率等时地层格架，分析了沉积演化过程、沉积相演化序列及砂体的空间展布规律。

| Abstract: | The architectures of three types of the short-term base-level cycles in the Chang-6_2 oil beds of the Upper Triassic Yanchang Formation in the Pingbei Oil Field,northern Shaanxi are described in detail. The high- resolution sequence stratigraphic division and correlation result in the construction of the isochronous stratigraphic framework,and the examination of the depositional evolution,sedimentary facies sequences,and spatial distribution of sandstones in the study area. |
