| 摘 要： | 该文利用油层温度和井温资料建立了江汉盆地拖市现代地温场分布，并估算了大地热流；采用镜质体反射率积分法计算了两期古地温梯度；用均一法实测硬石膏包裹体捕获古温度数据。结果表明，不同时期的热演化反映区域构造活动具有从东北向西南迁移的规律。根据热历史与成岩及构造演化之间的关系，讨论了导致该区域储层致密的主要因素硬石膏的充填与沉淀特征。

| Abstract: | The paper calculates the average paleo-geothermal gradients during Eq-Q and Es-Ejs by the method of vitrinite reflectance integration and determines the homogenization temperatures from the measurement of diagenetic fluid inclusion of fracture system, and establishes the current geothermal field and estimates the terrestrial heat flow. The results indicate that the geothermal evolution characters are corresponding to the migrating features from northeast to southwest of the tectonic active center. With this relationship, the filling and setting characteristics of the anhydrite have been discussed, which is one of the major factors of influencing the low-permeability reservoir in the area. |
