摘要:        针对海塔油田某高温高盐油藏断块水淹水窜现象严重的问题,研制了一种耐温耐盐的聚合物纳米微球PM-1体系,利用激光粒度分析仪和扫描电子显微镜评价了PM-1的微观形貌、粒径分布及吸水膨胀性能,最后借助岩心流动实验优选出了适用于试验区油藏的聚合物纳米微球调驱体系的最佳注入参数。结果表明,合成的聚合物纳米微球PM-1初始平均粒径为405.87 nm,具有很好的膨胀性能,在90 ℃的模拟地层水中,聚合物纳米微球吸水24 h后的膨胀倍数为35.52,优选出聚合物纳米微球PM-1体系最佳的注入参数为:聚合物纳米微球PM-1质量浓度为2 000 mg/L,注入体积为0.20 PV,注入速度为0.3 mL/min,注入方式为两段塞注入(0.1 PV微球PM-1+0.1 PV水+0.1 PV微球PM-1

Abstract:

        Aiming at the problem of water channeling in a high temperature and high salt reservoir in Haita oilfield, a kind of heat resistance salt resistant polymer nanometer microspheres PM-1 system was developed. The microscopic morphology, particle size distribution and swelling performance were evaluated by laser particle size analyzer and scanning electron microscope. Finally the suitable reservoir polymer nanomicrosphere injection parameters of oil displacement system for the test area were put forward by using core flow experiment. The results showed that the initial average particle size of polymer nanoparticles microspheres PM-1 was 405.87 nm and PM-1 had the very good performance, the swelling ratio ofPM-1 in 90 ℃ of simulated formation water was 35.52. By nanospheres parameter optimization experiments, injection parameters of the nanosphere system were optimized: injection at a concentration of 2 000 mg/L, injecting an amount of 0.2 PV, injection rate of 0.3 mL/min, injection method 0.1 PV microsphere+0.1 PV water+0.1 PV microspheres.
