地层基准面模式是高分辨率层序地层学理论的基石,伴随基准面的升降变化,可容纳空间增长速率与沉积物补给通量的比值不仅决定了地质作用全过程及旋回地层的发育,而且还直接影响着地层中砂体的空间展布规律及物性特征.在识别出不同级次地层旋回的基础上,高分辨率层序地层学的旋回等时对比技术使建立精确的区域地层对比格架成为可能. Stratigraphic basement model is the cornerstone of high-resolution sequence stratigraphy theory. With the change of base level, the ratio of admissible space growth rate to sediment recharge flux not only determines the whole process of geology and the development of cycle stratigraphy, but also But also directly affects the spatial distribution regularity and physical property of sand bodies in the strata.On the basis of recognizing different levels of stratigraphic cycle, the high-resolution sequence stratigraphy cycle isochronous technology makes the establishment of precise regional stratigraphic contrast Racks become possible.
