通过油/水、气/水三相实验来研究相对渗透率与润湿性的关系。利用X射线计算机辅助层析成象CT扫描仪.定量确定流体饱和度值。在某些情况下,发现了油气水的三维分布是极不均匀的,且与实验条件有关。实验结果表明,关于相对渗透率测量的某些传统看法可能是错误的,值得进一步研究。 The relationship between relative permeability and wettability was studied by oil / water, gas / water three-phase experiments. X-ray computed tomography (CT) imaging was used to quantify fluid saturation values. In some cases, the three-dimensional distribution of hydrocarbon gas was found to be highly inhomogeneous and related to experimental conditions. Experimental results show that some of the traditional observations about relative permeability measurements may be wrong and deserve further study.
