摘要
利用微分方程,结合达西公式,Klinkenberg关系,描述了氮气在岩心中非稳态的流动过程,推导了渗透率测量计算公式,利用此理论得出测量岩心渗透率的非稳态方法,此测试方法简单、快捷,且具有现实可行性。
Based on differential equation,considering Darcy law and Klinkenberg relationship,unsteady-state flow behavior of nitrogen in core is described and the calculation formula is theoretical derived.Based on the theory,an unsteady-state method of measuring gas permeability of core is given.The measurement method is simple and quick,and having feasibility.
