X-CT扫描技术与贝克莱-列维尔特水驱油理论对比研究流体饱和度分布

Comparison of X-CT Scanning Technique and Berkeley-Villewater Water-flooding Theory Fluid Saturation Distribution

应用X-CT扫描技术研究岩心中流体饱和度已经较为成熟,但是其与实测水驱油结果对比,目前还少有提到。主要通过自主研发的X射线扫描设备,进行室内水驱油实验,将X-CT扫描法得到水驱油过程岩心中油、水饱和度分布与油水计量法(JBN法)理论计算得到岩心中含水饱和度分布进行对比,了解到两种方法计算的含水饱和度分布基本一致,但是,X-CT扫描法的计算结果更能够准确描述岩心不同断面处含水饱和度分布的情况。基于此,首次提出了可通过对两种方法计算的含水饱和度曲线的对比分析,来检测JBN法得到的相渗曲线的正确性。

Application of X-CT scanning technology in the core of the fluid saturation has been relatively mature,but there are few articles mentioned to study this issue that comparison of X-CT scanning technique and Berkeley-Villewater water-flooding theory fluid saturation distribution.Mainly through the independent research and development of X-ray scanning equipment,indoor water flooding experiment,the X-CT scanning method to get water flooding process in the core of oil,water saturation distribution and oil and water measurement method（JBN method） theoretical calculation of the core The results show that the distribution of water saturation in the different sections of the core can be described accurately.However,the results show that the water saturation distribution is consistent with that of the X-CT scanning method.Based on this,the correctness of the seepage curve obtained by JBN method is proposed by comparing the water saturation curves calculated by the two methods.
