- 摘要:
- 针对污水在普通驱油用聚丙烯酰胺在配制过程中产生的不利影响，研究了一种提高驱油用聚丙烯酰胺分子链刚性的合成方法。通过在分子主链引入刚性功能单体，提高了共聚物在污水配制条件下的耐受能力；通过实验确定了单体配比、反应条件、引发体系各组分用量等关键影响因素，合成出了一种高刚性抗盐型驱油用聚丙烯酰胺。合成的高刚性抗盐型聚丙烯酰胺经性能研究，在耐剪切、粘度长期稳定性、驱油效果方面表现出超过普通驱油用聚丙烯酰胺的性能。Aiming at the adverse effects of sewage preparation on conventional polyacrylamide for oil displacement, a synthesismethod to improve the molecular chain rigidity of oil-displacement polyacrylamide was investigated. By introducing rigid functionalmonomers into the polymer main chain, the salt tolerance of the copolymer under sewage preparation conditions was enhanced. Thekey influencing factors, such as monomer ratio, reaction conditions, and dosage of each component in the initiation system, were de⁃termined through experiments, and a high-rigidity salt-resistant polyacrylamide for oil displacement was successfully synthesized.Performance evaluation results show that the synthesized polyacrylamide exhibits better shear resistance, long-term viscosity stabili⁃ty, and oil displacement efficiency than conventional oil-displacement polyacrylamide.
