基于CT扫描测定低渗岩心相对渗透率曲线的方法
Methods of Measuring Relative Permeability Curves with Low Permeability Core Based on CT Scanning
摘要
Abstract
The recovery scheme for most Chinas low permeability reservoirs is water flooding, however, it's difficult to get the key data of relative permeability in water flooding by conventional experiment. The steady state experiment and non - steady state experiment of getting relative permeability curves with low permeability cores is raised based on scanning. In steady state methods, in view of the fact that its difficult to get steady state, steady judgement bases are given based on CT scanning data. The adoption of 1 calibration method can overcome the influence of ray hardness, and therefore increases the accuracy of measuring fluid saturation by u-sing CT scanning. The test with 2 cores show that the method is practical and feasible.关键词
