| 摘 要： | 本文从长石溶解反应的机理及各离子形态在溶液中分布的热力学角度出发 ,论述了pH值对三个长石端员及高岭石在流体中溶解度的影响。在此基础上 ,进一步探讨了流体酸碱度对长石向高岭石转化和次生孔隙发育程度的制约 ,并提出了衡量次生孔隙发育程度的参数———转化系数D。

| Abstract: | In this paper, based on the mechanism of dissolution of feldspar and the distribution of various aqueous ions, the effects of pH on the solubility of three endmembers of feldspar and Kaolinite in fluid were studied from the angle of thermodynamic.The influence of pH of the fluid on the transformation of feldspar to kaolinite and the development of secondary porosity in this process were further studied. coefficient of transformation ( D ) was offered to estimate the degree of the development of secondary porosity. |
