| 摘 要： | 采用双段塞法分析了部分水解聚丙烯酰胺 (HPAM)的相对分子质量、岩心孔隙分布、温度及矿化度对聚合物的不可入孔隙体积 (VIP)的影响规律。分析结果表明 ,VIP随HPAM的相对分子质量的增大而增大 ;VIP随着岩心平均孔隙半径增大、温度升高、矿化度增加而减小。在不断变化的地层条件下 ,HPAM的VIP可能出现高值的现象 ,这将严重影响聚合物驱的波及系数 ,从而使聚合物驱的原油采收率降低。 |
| 关 键 词： | 双段塞法 聚合物驱 不可入孔隙体积 岩心 孔隙分布 温度 矿化度 |

| Abstract: | The effects of different relative molecular weight of partially hydrolyzed polyacrylamide (HPAM), pore size distributions of cores, different temperatures and salinity on the inaccessible pore volume (V_(IP)) of HPAM were studied by using double-slug method. The analysis results proved that V_(IP) increased with the increment of the relative molecular weight of HPAM and decreased gradually with the increase of the average pore radius of core, temperature and salinity. Under the varying conditions of formation, the increment of the V_(\%IP) of HPAM may be prominent, which has a great influence on the sweep coefficient of the polymer flooding and reduce the oil recovery efficiency of polymer flooding. |
| Keywords: | double-slug method polymer flooding inaccessible pore volume core pore size distribution temperature salinity |
