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 test device was designed and tested to measure the gas slip factor b and the core Kref permeability K ∞. The test principle is based on a new method for determining the core permeability Kg of a core. Using this method, multiple pressure and time points can be recorded during a pressure drop to calculate multiple Kg values, then b and K∞ can be obtained by least-squares fitting. Repeatability testing of the test device shows that the device is stable and reliable.
