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bK。对测试装置作的重复性测试表明该装置是稳定、可靠的。

Abstract: 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.
