| 摘 要： | 通过岩样应力应变全过程体积应变和渗透率的试验研究，分析了应力水平、孔隙率等对多孔介质岩体渗透率的影响规律；理论研究分析了岩样全应力应变过程渗透率的变化规律，提出了岩石应力应变全过程中渗透率的表征关系式，其可作为研究多孔介质岩体流固耦合的一个重要耦合关系式，并对今后低渗透性油气田煤层气、天然气的开发有现实的指导意义。

| Abstract: | Based on the experimental study on the volume strain and permeability of rock samples, the characteristic of permeability affected by stress level and porosity are analyzed, the variable regularity of permeability of rock mass during the complete stress strain course is studied by theoretical analysis, and the characterization relation formula of permeability during the whole stress strain course is proposed. The characterization relation formula can be used as an important coupling relation formula while studying the coupling problem between flow and solid. The results give a definite path for the exploitation of coal gas and natural gas of lower permeability fields. |
