摘　　要：利用砂岩微观模型两相驱替实验方法，研究了靖安油田长２、长６油层的润湿性，并分析了地层水性质和岩石矿物成分对油层润湿性的影响。结果表明：长６油层润湿性为弱亲水—中性，长２油层明显为亲水油层；该结论与常规吸入法所得结论一致。The wettability of Jing′an Oilfield in two phase displacement experiment was studied by sandstone micro model.The results show that the character of formation water and composition of rock or oil affect the wettability to certain extent.The conclusion can be drawn such as: the wettability of Chang 6 formation in Jing′an Oilfield is weakly water wet or mid wet instead of clearly water wet in Chang 2.The result is very closely to that by the normal imbibition method.
