摘要
受岩石样品夹持器形状结构的限制,岩样必须加工成规则圆柱状才能测定渗透率。这种岩样外形的限制性要求,使得同一样品测定三个方向的渗透率难以实现。本文提出了一种岩样三向渗透率测定方法,这种方法通过使用岩心分析测试用过渡套(ZL201120152706.1)以及一种岩样三向渗透率的检测方法及其检测系统(201210400962.7),利用过渡套外圆内方的结构特点,将正方体岩样按照标注好的方向先后放入过渡套中,再分别进行三个方向的渗透率测试,从而得到同一样品三个方向的渗透率数据。9块泥岩、泥灰岩样品实验表明,样品渗透率各向异性显著,这种方法的应用不仅能够节省样品,减少工作量,还能提高样品渗透率各向异性信息的可比性,具有良好的应用前景。
According to this method,the cube rock samples can be put into the transition units followed the marked direction in accordance with the structural characteristics of the transition units,and then the permeability test will be carried out in three directions respectively.After that,the three-dimensional permeability datas of the same sample can be obtained.Nine rock samples,including shale and marlstone,are selected to test the experiment,the result shows a significant anisotropic permeability.This method has the advances of saving samples,reducing the workload,improving the comparability of anisotropic permeability,can be applied well in the future.
