摘要
The data from typical boreholes in the southern Jianghan basin were modeled using the geothermal history simulation system of hydrocarbon-bearing basin, and the thermal history and burial history were reconstructed. Based on the thermal history, maturity evolution of the Lower Silurian source rocks was modeled. The results show that the basin was in a stable stage before Indosinian movement, the paleo-heat flow was between 50 mW/m2 and 55 mW/m2. After Indosinian period, the heat flow was elevated in the whole basin. In Yanshan period (155 Ma or so), the heat flow reached their maximum values of ～72 mW/m2 at 155 Ma in the north of the Qianbei Fault, the heat flows reached their maximum values of ～76 mW/m2 at 40 Ma in the south of the Qianbei Fault.
