摘    要:针对长庆靖安油田长6油藏高矿化度条件,对硬颗粒及软颗粒调剖剂的膨胀倍数、抗盐性、抗温性、注入性、剖面改善程度及驱油效果进行了综合评价。结果表明,在高矿化度条件下,硬颗粒与软颗粒调剖剂相比,具有膨胀倍数高、耐温抗盐性好、提高采收率潜力大的特点。可选用硬颗粒调剖剂,用自来水配制调剖体系,以发挥其显著的膨胀能力,有效封堵大裂缝出水通道。

关 键 词:颗粒调剖剂  硬颗粒  软颗粒  高矿化度  性能评价

Abstract:The profile control agents of rigid particle(precrosslinked particle)and soft particle(waterflooding flow direction altering agent)were evaluated,including their expansion velocity,salt tolerance,heat resistance,injection property,extent of profile improvement and EOR efficiency,under high mineralized condition simulated Chang-6 Reservoir in Changqing Jing'an Oilfield.The results showed that the rigid particle was better than the soft particle in expansion,salt tolerance,heat resistance and EOR efficiency under high salinity condition.The rigid particle profile control system prepared with fresh water was suitable to in-depth profile modification,with high expansion rate.It might be used to block big water-producing fractured channels.
Keywords:particle profile control agent  rigid particle  soft particle  high mineralizing rate  property evaluation
