本文利用甾烷异构化指数随时间、温度变化规律、采用热指标反演拟合法建立了非线性，反演波动热流模型，分构造运动期模拟古热流。实现了甾烷异构化指数恢复油气盆地热演化的定量化。运用上述方法，对海拉尔盆地海参１井进行了热史模拟。得到了盆地源岩热演化的一般规律。
In this paper, a non-linear and inversely fluctuating heat flow model was established by using the thermal index inversion fitting method based on the regularity of the isomerization index of steranes with time and temperature, and simulated the paleokraft flow in the tectonic movement period. The quantification of thermal evolution of oil and gas basin by the isostane isomerization index was realized. Using the above method, the thermal history of sea cucumber 1 in Hailaer Basin was simulated. The general law of thermal evolution of source rocks in the basin has been obtained.
