摘要
以组成均一的疏水缔合聚丙烯酰胺(HAPAM)与聚丙烯酰胺(PAM)为对象,在模拟我国主力油藏条件下研究了HAPAM与PAM的驱油性能。结果表明,HAPAM比PAM有更好的驱油性能,特别是在注入0.4～0.5PV时,提高采收率约高出2%～4%;HAPAM浓度对驱油性能影响十分明显,但当HAPAM浓度达到2000mg/L,原油采收率增幅减缓;HAPAM表现出比PAM更好的耐温抗盐性能。
Hydrophobically associating polyacrylamide(HAPAM)and polyacrylamide(PAM)were investigated for enhance oil recovery at simulated Chinese major oil reservoir.It indicated that HAPAM has better oil displacement property than that of PAM.When the injected volume of polymer solution was 0.4~0.5PV,the increased efficiency of enhance oil recovery is about 2~4%.The effect of HAPAM concentration on enhance oil recovery is very obvious when the HAPAM concentration was lower than 2000mg/L.But when the HAPAM concentration reached 2000mg/L,the amplification of recovery ratio would slow up.HAPAM could also exhibit better thermal stability and salt resistance than PAM.The displacement pressure and oil displacement efficiency were increased with the increasing of HAPAM injected volume.
