摘要
从应力场作用的观点分别讨论了陕甘宁盆地两种主要储气类型的渗流问题。提出了渗滤作用的描述方法，从岩石内部结构应力作用变化的机制，得到了裂缝－溶蚀孔洞型碳酸盐岩的岩石渗透率与净围压的关系。利用该方法对该盆地的大量岩心进行了分析和实验研究，得到了与实际基本吻合而又十分有意义的结论。
The percolation flow properties of two main gas-bearing structures in Shanganning basin are studied based on analysis on stress field. A method to discribe the percolation flow properties is developed through the study. By means of the method, a large number of experiments on many cores have been carried out and the conclusions are significant and basically consistant with those obtained from the theoretic analysis.
