The wettability of a formation is defined as the tendency of one fluid to spread on a surface in competition with other fluids which are also in contact with it. However, the impact of temperature on wettability in an aquifer and the modification of relative permeability curves based on the temperature variation in aquifers is not well covered in the literature. This study redresses this dearth of information by investigating the impact of temperature on wettability distribution in a reservoir and updating the relative permeability curves based on its temperature propagation. The impact of the latter is studied in relation to the solubility of CO₂ injected into an aquifer using the numerical methods (i.e. ECLIPSE). If the CO₂ injected has a temperature higher than the formation geothermal temperature, it can change the wettability of the formation further to a more CO₂ wet condition. This increases the risk of leakage and also changes the relative permeability curves as the CO₂ moves through the reservoir, a situation that needs to be considered in reservoir simulations. The results show that updating and modifying the relative permeability curves with temperature variation in an aquifer can increase the amount of CO₂ dissolution there.

地层的可湿性定义为一种流体与其他也与之接触的流体竞争而在表面上扩散的趋势。然而，文献中没有很好地涵盖温度对含水层中润湿性的影响以及基于含水层温度变化的相对渗透率曲线的修改。这项研究通过研究温度对储层中润湿性分布的影响并根据其温度传播更新相对渗透率曲线来解决这种信息匮乏的问题。使用数值方法（即ECLIPSE），针对注入到含水层中的CO ₂的溶解度研究了后者的影响。如果CO ₂注入的地层温度高于地层地热温度，它可以进一步将地层的润湿性改变为更高的CO ₂润湿条件。这会增加泄漏的风险，并且还会随着CO ₂穿过储层而改变相对渗透率曲线，这种情况需要在储层模拟中加以考虑。结果表明，随着温度的变化而更新和修改相对渗透率曲线可以增加那里的CO ₂溶解量。
