In sequence stratigraphic system, vertical development of the reservoir is controlled by base level cycle changes, and spatial distribution is restricted by the palaeogeomorphology.
在层序地层体制中，储层的纵向发育受基准面升降变化旋回的控制，而平面展布受古地貌的制约。

Base on the discerning of different levels base-level cycle, the chronostratigraphic correlation can provide guides to establish precise stratigraphic frame.
