| 摘 要： | 为了提高层序地层分析的分辨率和储层预测的准确性，运用ＣｒｏｓｓＴＡ等人倡导的地层基准面原理，对ＴＣ２井进行了基准面旋回识别和高频层序划分，中期旋回与层序相对应，一般表现为完整的基准面上升和下降旋回，只有冲积层序（Ｓ１１、Ｓ１２、Ｓ１３）缺失下降旋回沉积；上升包括低水位和水进体系域；下降旋回属高水位体系域 ，其转折点肉麻 段；短期旋回相当于层序。所识别出的３种准离类型茏典层序地层学的概念有所不同。研

| Abstract: | Base-level circles and high-frequency sequences for the formations of well tc2 were identified in the light of stratigraphic base-level principle proposed by t. A. Cross. The middle circle fits the sequence, which is indicated by a whole base-level rising and downward circle, and only the fluvial sequences (s11, s12, s13) lack downward circle deposition; the rising circle includes low-stand and water progradation system; the downward circle belongs to high-stand. The results are significant for accurate correlation of sand layers and prediction of reservoirs in the studied area. The three types of parasequence were distinguished in this paper, which are different from the concept of classic sequence stratigraphy. |
