摘　　要：设计、制作了一台可测试气体滑脱因子b及岩芯克氏渗透率K∞的测试装置,其测试原理基于一种测定岩芯气测渗透率Kg的新方法。利用这种方法,此装置可在一次压力下降过程中记录下多个压力、时间点,从而计算出多个Kg值,然后经最小二乘拟合得出b和K∞。对测试装置作的重复性测试表明该装置是稳定、可靠的。A device is developed for measuring the gas slip factor b and intrinsic permeability K∞.The theory of operation is based on a new method of measuring the gas permeability Kg.By this method,many time-pressure data points are measured during the process in falling of pressure,thus,several data of Kg are calculated,and after that,the gas slip factor b and intrinsic permeability K∞ can be obtained by the way of least squares.A test to the repeatability shows that the device works reliably.
