摘要
储集层岩石的渗透率性质存在方向上的差异，此即各向异性性质，该性质与组成岩石颗粒的排列有序程度有 关，排列有序程度越强，各自异性越严重；储集层岩石的渗透率性质还同时存在不对称性，该性质也与组成岩石颗粒的 排列有序程度有关。作者指出，各向异性和不对称性是岩石渗透率性质的基本特征，并给出了不同参数定量描述的方 法。在生产实践中，可根据具体情况充分利用岩石的这些性质。
The presence of orientational differences in reservoir rock permeability, called anisotropy, is related to the arrangement of particles that form rocks. Meanwhile, there exists asymmetry in permeability, which is, like anisotropy, related to that of particles, too. According to the basic characteristics in rock permeability, quantitative description methods of these by using different permeability parameters are presented, thus providing useful basis for in-depth study of the reservoir rocks and their oil/gas percolation.
