本文讨论了粘土矿物转化的化学动力学模型及其应用。对于某一地区，粘土矿物蒙皂石向伊利石的转化主要受温度和时间的影响，可以用化学动力学一级反应的模型描述，这一模型可用于：（１）反演古大地热流；（２）模拟成岩史；（３）在盆地内没有钻井的区域预测地层的成岩阶段。
This article discusses the chemical kinetic model of clay mineral conversion and its application. For a certain area, the conversion of clay mineral smectite to illite is mainly affected by temperature and time. It can be described by the model of first order reaction of chemical kinetics. This model can be used to: (1) Retrieve ancient geothermal heat; (2) simulating diagenetic history; and (3) predicting the diagenetic stage of the strata in areas not drilled in the basin.
