Abstract: Based on the results of study of unsteady state method,a new method is suggested in this paper. By means of "mechno-electric analogue method", core sample in a pressured container is simulated by an equivalent electrical resistance, R; and containers on the upstream and downstream side of the core sample is simulated by an electrical capacitance,C. A,physical model as well as a mathematical model is then constructed. Experimental studies by means of this model have been carried out and the results obtained are con-sistant with those obtained with corresponding theoretical model,thus, dificiencies in the measurement of parameters on a core sample with a permeability of ≤10^-5μM², and a porosity of ≤3.5% can be overcome.

摘要： 这项研究,是在80年代国外有关非稳态方法研究的基础上,利用机电模拟方法,把处于压力容器中的岩样模拟为电阻R,样品上、下流容器模拟为电容器C得到的物理模型和数学模型.根据这个模型进行了实验研究,得出与理论模型相一致的结果,因此克服了传统测量渗透率的方法和模型对渗透率≤10^-5μm²,孔隙度≤3.5%以下致密岩石存在较大测量误差的缺陷.
