| 摘 要： | 综合运用现代油气地质理论及镜质组反射率测定等现代分析测试方法，分析了渤海湾地区的构造演化及古地温场特征；采用EASY％R。数值模拟技术对大量钻孔进行了埋藏史反演，首次较为细致合理地恢复了渤海湾地区三叠系原始沉积厚度。结果表明：华北晚古生代巨型沉积盆地的发育历史一直延续至印支中期，古生界在印支期末埋藏可达2500－4000m，埋藏深度及其在空间上的展布特征主要受控于三叠系统的原始沉积厚度。

| Abstract: | The tectonic evolution and paleogeothermic field in the Bohaiwan Basin were analyzed based on the modern oil and gas geological theories and using the new method of measuring vitrinite reflectance. Having analyzed the data from a number of boreholes in the Baohaiwan Basin using the EASY% R o numerical simulation, the author revealed the depositional framework of Triassic for the first time. The result shows that the development history of the huge depositional basin of Late Paleozoic in Huabei area lasted to the middle period of the Indosinian movement, and the embedding depth of Paleozoic source rocks is from 2500 m to 4000m. The embedding depth and space distribution of Paleozoic source rocks was mainly controlled by the original depositional thickness of Triassic system. |
