裂缝—溶蚀孔洞型碳酸盐岩储层是陕甘宁盆地中部气田主要的天然气储层之一，其特征表现为连片的溶蚀水平孔、洞与微细裂缝相连通。文章建立了符合该储层结构的特征模型，并从应力场作用的观点出发，讨论了渗流过程中储层岩石的约束应力作用与渗透率之间的理论关系，运用建立的岩石渗透率与净围压的关系式计算得到的数据，同实验得到的结果十分接近，达到了预期效果。
Crack-dissolving-hole carbonate reservoirs are one of the major gas reservoirs in the gas field in the central Shaanxi-Gansu-Ningxia basin. They are characterized by contiguous horizontal erosion holes that communicate with fine cracks. In this paper, the characteristic model accorded with the reservoir structure is established. From the viewpoint of the stress field, the theoretical relationship between the constrained stress and the permeability of the reservoir rock during the seepage process is discussed. By using the established permeability of the rock and the net Computation of confining pressure data obtained with the experimental results are very close to achieve the desired results.
