X-CT扫描技术与贝克莱一列维尔特水驱油理论对比研究流体饱和度分布

应用X-CT扫描技术研究岩心中流体饱和度已经比较成熟了,但是其与实测水驱油结果对比,目前还少有文章提到,本文针对这个问题进行研究。主要是通过自主研发的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。基于此首次提出了通过对两种方法计算的含水饱和度曲线对比来检测JBN法得到的相渗曲线的正确性。

Study on the distribution of fluid saturation by X-CT scanning technique and Bekele water displacement theory

Application of X-CT scanning technology in the core of the fluid saturation has been relatively mature, but there are few articles mentioned in this paper to study this issue by means of comparison of X-CT Scanning Technique and Berkeley-Villewater Water-flooding Theory. Mainly through the X ray scanning equipment and independent research and development of indoor water flooding experiment, the X-CT scanning method to get water flooding oil core oil, water saturation and oil-water distribution measurement method (JBN method) were calculated comparing rock water saturation distribution.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 relative permeability curve obtained by JBN method is proposed by comparing the water saturation curves calculated by the two methods.
