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.
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。
The presence of aggregates in cement-based materials might modify the pore structure of hardened cement paste, and its dilution effect and tortuosity effect could reduce chloride transport properties.
骨料改变了水泥基复合材料中浆体的孔结构，其稀释效应和曲折效应降低了氯离子的传输性能；
