硬脆性泥页岩水化过程的微观结构变化
摘要
Abstract
In order to solved the wall instability problems of the clay shale formation, we used X - ray diffraction scanning electron microscope and digital core analysis of CT imaging equipment, tested the core of the Xujiahe three sections in Chuanxi, analyzed the change and law of the microstructure process in hydration process of clay shale. The results showed that the capillary effect of the natural micro-porous seam in mineral grains promoted the internal hydration, the hydration promoted the generation of the secondary hole and fissure, such mutual promotion was one of the primary cause that generated the microcosmic structure change or even damage. The initial microscopic structure occurred mainly in the mineral particles that contact for surface-face or point-to-face structure interface. The change of the microscopic structure expanded and extended evolution of the microscopic cracks.关键词
