| 摘 要： | 稠油蒸气吞吐开采过程中，注入储层的高温水蒸气与储层岩石发生了强烈的水岩作用，使注入水的化学成分产生了显著的变化，根据这种变化，结合水岩作用室内模拟实验的研究成果，在确定水岩作用方式的基础上，使用元素质量守衡计算方法对辽河曙光油田的水岩作用量进行了计算，结果表明，注入水在储层运动过程中，溶解了大量的石英和高岭石，同时沉淀出大量的钠蒙脱石，该结果很好地吻合了室内实验成果。

| Abstract: | In the process of heavy oil heat explotation, the injected high temperature water steam can react intensely with reservoir host rock. This can cause obvious change of injected water composition.According to this change, on the basis of determination of water rock interaction mode,the amount of water rock interaction can be determined using mass balance calculation method .The calculated results of Liaohe Shuguang Oil Field showed that in the process of heavy oil heat exploitation, the injected water dissolved large amount of quats and kaolinite,precipitated large quantity of sodium montmorillonite at the same time. This is in good agreement with laboratory experimental results. |
