| 摘 要： | 以孔隙喉道半径与聚合物分子线团回旋半径比（r_h／R_G）作为聚合物与岩心配伍性的特征参数，检验了国内外发表的和本文作者所作的聚合物IIPAN溶液岩心流动实验数据。在可比条件下，对于环氧树脂胶结的人造岩心，聚合物通过而不堵塞孔隙的条件是r_h／R_G＞5；对于地层岩心，此比值应更大。在大庆油田聚合物驱中，建议取r_h／R_G为5－10。

| Abstract: | The meanings of and the calculating equations for gyration radius,R_G,of polymer coil in dilute HPAM flooding solutions and for different pore radii (pore radius medium valwe. r_50,equivalent pore radius. r_eq, and pore throat radius,r_h) are presented. The ratio r_h/R_G is selected as a characteristic of adaptivity of polymer molecular mass to core permeability after analysing a lot of experimental data published and obtained obtained by the authors of this paper. It is shown that for epoxy resin-consolidated cores the r_h /R_G value must be >5 and for formation cores larger r_h/R_G value is preffered in core flow experiments, In polymer flooding operations in Daqing Oil Fields this is recommended to be 5 10. |
