这些区域可能是天然的页岩透镜体，也可能是在EOR方法中注入聚合物人为所致。
These regions may be shale lense or artificially introduced in an EOR like process, such as polymer flooding.
对于地层非均质性的影响，通过注入聚合物段塞调驱，能起到防止气窜，增加注入气驱扫效率。
Prepositive polymer slug displacement can decrease the effect by the formation heterogeneity, prevent the gas breakthrough and improve the displacement sweep efficiency of the injective gas.
通过分析认为，储层经过长期注入聚合物后，使一部分小喉道变大，孔隙之间的畅通性进一步变好，孔隙迂曲程度减小。
It is suggested that the long-term polymer drive has resulted in enlarging some small pore throats, improving the communication among pores and reducing pore tortuosity in the reservoirs.
