从现场上各种水淹的实际资料来看，同一水动力的非均质油层系统中，渗透率相对较高的部分水洗之后，渗透率相对较低部分的油层却可以原封不动。而且，其渗透率可达达西级，含油饱和度可达80％以上。相对流动比(即同一水动力的非均质油层系统中，小层平均渗透率的最大值与其中不流动部分的小层平均渗透率的最大值相比)的比值在各种油层的生产实例中十分相近。一般的分布范围为3—7，常见的为4—6。实验室结果和生产实践基本相同。简单的注水和压裂对这一比值几乎无影响。

Changbei gas field is a river lothology-stratigraphic trap gas pool on the west trend monocline background, it is located in the east of the basin, it has thin bed, low-porosity, low-permeability, low-pressure, low-deliverability character and develop difficulty(HeGuang-huai, 2002), especially to develop this thin bed and unhomogeneity seriously river sandbody gas pool is much difficulty.
