混相驱替中多孔介质渗透率非均质性是用标准压力和生产史的测量进行评价的。在具有流度比的生产史中的变化和理想响应压力史间的偏差为渗透率非均质性提供了佐证资料,这些非均质性试验已经发展到有助于对不稳定相对渗透率试验和其他不稳定驱替试验的岩心样品的选择。
Permeability heterogeneity of porous media in mixed-phase flooding is evaluated using measurements of standard pressure and production history. Deviations in the history of changes in the production history with a flow ratio and the history of ideal response pressures provide corroborating information on permeability heterogeneity that has been developed to help test the relative impermeability And other unstable displacement test of the core sample selection.
