中文摘要:
      针对胜利油田高温高盐的油藏环境,设计合成了一种具有梳型结构的疏水缔合聚合物,系统考察了该聚合物溶液的增粘性、耐温抗盐性、长期稳定性、注入性和驱油效果。实验结果表明,随着浓度的增加,溶液粘度呈指数增长,增粘性强。在高温高盐条件下,该疏水缔合聚合物溶液粘度均比常规聚丙烯酰胺溶液高,表现出优异的耐温抗盐性能。在90℃条件下,随老化时间增加,溶液粘度先增加后降低,60天后溶液粘度值大于40mPa.s,表现出优异的长期稳定性。随注入量增加,压力先增加后趋于平衡,达到0.5Mpa,表明其注入性良好。当注入浓度一定时,随着注入倍数的增加,提高原油采收率幅度先增大后趋于稳定;当注入倍数一定时,随疏水缔合聚合物浓度的增加,提高采收率幅度增大。
英文摘要:
      Aimed at the high temperature and high salinity reservoir in ShengLi oilfield, a kind of comb-like hydrophobic associated polymers (HAWSP) has been synthesized. The capacities of increasing viscosity, heat resistance and salt tolerance, long -term stability, injectivity and oil displacement efficiency were studied. Results showed that with increasing concentration, the viscosity of HAWSP increased exponentially. Under the condition of high temperature and high salinity, the viscosity of HAWSP was larger than that of hydrolyzed polyacrylamid (HPAM), showing good heat resistance and salt tolerance. At the ageing time of 90℃, the viscosity of HAWSP increased first and then decreased over time, and it was larger than 40 mPa.s after 60 days, indicating excellent long-term stability. Injection performance test showed that with increasing injection volume, the pressure increased first and then became balanced with 0.5 MPa, indicating good injectivity. When injection concentration was constant, the oil recovery increased first and then became balanced with the increasing injection volume; when injection volume was constant, the oil recovery increased with the increasing concentration of HAWSP.
