| 摘 要： | 测量岩石的渗透率在油田、水利、废物处理和环境工程等领域具有重要意义。在已有的高压孔隙度渗透率测量仪上,根据Darcy定律、状态方程和质量守恒方程,研究了一种气体介质渗透率瞬态测量和计算方法。结果表明,这种方法对低渗透率岩芯测量简单快捷,而且易于推广到温度条件下的渗透率测量。

| Abstract: | Measuring permeability of rock has important meaning in oil field, water conservancy, waste dispose and environment engineering. Using the Porosity and Permeability Meter under high pressure, based on Darcy law, state equation and equation of continuity, a gas transit measurement and calculation method of permeability on rock has been studied. The results show that the method is suitable to low permeability rock, quick and simple as well. Meanwhile, it is easily extended to permeability measurement under temperature condition. |
