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。注稠化水等措施是改造这种油层的方向,但最终界限目前还不好确定。浊层研究、油田开发和各种油井工程措施应当考虑相对流动比这一因素。
According to the actual data of all kinds of flooding on the spot, in the same hydrodynamic heterogeneous reservoir system, the reservoir with the relatively lower permeability can be left intact after the part with relatively high permeability is washed by water. Moreover, its permeability up to Darcy level, oil saturation up to 80%. The ratio of the relative flow ratio (ie, the maximum value of the average permeability of the small layer to the maximum value of the average layer permeability of the non-flowing part in the same hydrodynamic heterogeneous reservoir system) Very similar. The general distribution of 3-7, the common 4-6. Laboratory results and production practices are basically the same. Simple waterflooding and fracturing have little effect on this ratio. Note thickening water and other measures to transform the direction of this reservoir, but the final boundaries are not yet sure. Turbidity studies, field development and various well engineering measures should take into account the relative flow ratio of this factor.
