| 摘 要： | 通过碳酸盐（方解石、白云石）溶蚀作用实验室模拟研究，建立了溶蚀作用的热力学模型方程，对埋藏成岩的3种不同温压条件下（348．15K，Mpa ,373．15K，25Mpa，403．15K，30MPa）碳酸盐溶蚀作用进行了定量研究。提出随着温度和压力的升高，碳酸盐溶解反应的吉布春播由能降低，因而溶解反应增强；在相同温度和压力的地质条件下，白云石较方解石更易溶蚀并形成次生孔隙，这为油气生成运移提供了有利的地下空间和通道。

| Abstract: | The dissolution of carbonate rock has been simulated by testing,the thermodynamic equation of dissolution reconstructed and the dissolution quantitatively studied under different temperature and pressure(348.15 K,20 MPa;373.15 K,25 MPa;403.15 K,30 MPa).The dolomite is much more easy to dissolute than limestone. At the same time, the underground engineering geologic outline is to be considered on the location of downtown, railway, tunnel and so on so as to appear natural geological disasters. |
