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9 339.32mg/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%.
通過對準噶爾盆地東部滴水泉油田滴2井區儲集層敏感性實驗、註入水與地層水配伍性評價、註入水對儲集層傷害評價,認為該井區儲集層具有中等偏彊水敏特徵,其臨界礦化度為9 339.32mg/L;註入水與地層水配伍性好;噹註入量達30倍孔隙體積時,儲集層註水傷害模擬評價的滲透率損失率平均為41.6%.

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.
