| 摘 要： | 通过对准噶尔盆地东部滴水泉油田滴2井区储集层敏感性实验、注入水与地层水配伍性评价、注入水对储集层伤害评价,认为该井区储集层具有中等偏强水敏特征,其临界矿化度为9339.32mg/L;注入水与地层水配伍性好;当注入量达30倍孔隙体积时,储集层注水伤害模拟评价的渗透率损失率平均为41.6%.

| Abstract: | This paper presents the evaluations of the injected water and formation water compatibility and the injected water on reservoir damage through Di-2 well area's reservoir sensitivity experiment,showing that this reservoir is of medium-serious water-sensitivity,with critical salinity of 9 339.32 mg/L,good compatibility,and when injected rate is up to 30 times of pore volume,the permeability loss factor is up to 41.6% in average by simulated evaluation of reservoir damage due to water flooding. |
