摘要
论述了复合离子聚合物调驱剂的成胶时间长且可控,有良好的抗盐性、抗剪切性、热稳定性等优点。综述了影响复合离子聚合物调驱剂成胶性能的因素主要有组成调驱剂的各化学剂用量、复合离子聚合物相对分子量、剪切强度、矿化度、pH值等。复合离子聚合物调驱剂用量和调驱时机对调驱效果也有显著影响。复合离子聚合物调驱体系适合应用在高含水、吸水剖面差、层间矛盾严重的中高渗油田,该调驱体系已在大庆油田得到广泛应用。虽然复合离子聚合物调驱体系在矿场应用中已经取得了一定成绩,但也存在一些问题,如驱油理论及评价方法不健全、生产成本较高、与多种调驱技术联用研究较少等。
The amphoteric polymers profile control-displacement agent has the advantages of long gelation time and controllability,and has good salt resistance,shear resistance and thermal stability.The factors that affect the cementing performance of amphoteric polymers are the amount of each chemical agent,the relative molecular weight of amphoteric polymers,shear strength,salinity,pH value and so on.The dosage of amphoteric polymers and the timing of profile control also had significant effects on profile control.The amphoteric polymers profile control-displacement system is suitable for middle and high permeability oil fields with high water cut,poor water-absorbing profile and serious inter-layer contradiction.This system has been widely used in Daqing oil field.Although the amphoteric polymers profile control-displacement system has made some achievements in the oil field application,there are still some problems,such as unsound oil displacement theory and evaluation method,high production cost,and few studies on the combination of various profile control-displacement technologies.
