进行三相油／水及气／水实验是为了研究相对渗透率与润湿性间的关系。用X-射线计算机辅助层面X线照相扫描仪定量确定流体饱和度。实验中发现油、水和气分布是三维的，在有些情况下呈高度非均质性，并受实验条件的影响。实验结果表明，某些传统的测定相对渗透率的方法有可能是错误的，值得做进一步研究。
The three-phase oil / water and gas / water experiments were conducted to study the relationship between relative permeability and wettability. Fluid saturation was quantified using an X-ray computer-aided tomography scanner. The experiment found that oil, water and gas distribution are three-dimensional, in some cases highly heterogeneous and subject to experimental conditions. Experimental results show that some of the traditional methods of determining relative permeability may be wrong and deserve further study.
