摘要
Abstract
JBN method is compared with Jones′ graphical technique by formula deriving and converting. It is concluded that the essential difference between the two methods is the different reference permeability of the rock. When calculating relative permeability,oil permeability at irreducible water saturation is a more suitable reference than the flowing ability of oil and water. The author made a comparison among Polynomial function,logarithmic function and exponential function when fitting average water saturation and total injection volume. The result shows that logarithmic function and exponential function have good fitting accuracy if piecewise fitting is carried out. Furthermore,oil ratio calculated by these two fitting function is more reasonable. We obtain similar oil relative permeability but quite different water relative permeability when using different functions to fit 1/Qi and 1/(IQi). Linear function,polynomial function and power function are compared,and the result calculated by power function is more reasonable.关键词
