鄂西溇水上游碳酸盐岩分布区岩石的溶蚀试验研究
- Title:
- Study on Dissolution Test of Carbonate Rock Sample from the Upstream Region of Lushui in West Hubei
- 分类号:
- TU458
- 摘要:
- 对碳酸盐岩类岩石样品的溶蚀试验表明，岩性对溶蚀的影响主要表现为各类岩石在启动溶蚀速率上的差异.在相同温压、相同比表面积的条件下，灰岩类岩石样品的启动溶蚀速率大于白云岩类岩石样品的启动溶蚀速率.但当样品在水岩反应过程中有不同的比表面积时，溶蚀作用的强弱或快慢就取决于岩石溶蚀速率与水岩反应有效接触面积的消长关系.
- Abstract:
- Test of carbonate rock sample’s dissolution reveals that lithology’s effects on dissolution mainly lie on their different start-up dissolution velocities.In the same conditions of temperature, pressure and specific surface area, the start-up dissolution velocity of limestone sample is more than the dolostone’s one.However, when the samlpes have different effective contact areas, the degrees of dissolution may depend on the swing of the pendulum between the dissolution velocity and their effective contact area.
