根据区内钻井测温和镜质体反射率（Ro）资料，采用岩石圈和盆地尺度相结合的分段线性热演化模型，对该区的热史进行了恢复。结果表明：（1）该区自古新世以来，热流的演化形态近似于“马鞍型”，中间有二次回升，但回升的幅度逐渐变小；古新世早期的大地热流值为83．6mW／m2，相当于现代活动裂谷的热流值，今大地热流值为63mw／m2,接近全球大地热流的平均值。（2）该区主力烃源岩经历了持续的受热过程，现今仍处于“生油窗口”内，在深度上具有较大的油气赋存空间，热演化背景十分理想。上述模拟结果可以用渤海湾盆地的裂谷演化模式进行较好的解释，并对胜利油田沾化凹陷的油气勘探工作具有一定的指导作用。
Based on the data of drilling temperature and vitrinite reflectance (Ro) in the area, a piecewise linear thermal evolution model combining lithospheric and basin scales was used to recover the thermal history of the area. The results show that: (1) Since the Paleocene, the evolution pattern of heat flux is similar to that of “saddle type” with the second rebound in the middle, but the amplitude of the rebound gradually decreases. In the early Paleocene, the terrestrial heat flow was 83.6mW / M2, which is equivalent to the heat flow value of the rifting in modern activities. The present geothermal flow value is 63mw / m2, which is close to the average of the global geothermal flow. (2) The main source rocks in this area have undergone a continuous heating process and are still in the “oil-generating window” at present, with large reservoir space for oil and gas in depth, and the background of thermal evolution is very ideal. The above simulation results can be well explained by the rift evolution model of the Bohai Bay Basin and have some guidance on the oil and gas exploration in the Zhanhua sag in the Shengli Oilfield.
