并且，对于具有二元结构的正旋回储层来讲，纵向上存在一定的非均质性。

Moreover, there is the vertical heterogeneity in the positive rhythmic reservoir which has binary structure.

在中长期基准面上升旋回内形成向上物性变差的层间非均质格局，而在中长期下降期则形成向上物性变好的非均质性格局。

In the rising semi-cycle of long-and medium-cycles, the reservoir became poorer from bottom to top, while it became better in the falling semi-cycle.
