| 摘 要： | 北萨哈林盆地作为俄罗斯远东地区最大的含油气盆地，其热流分布和演化过程对油气勘探有重要意义。本文通过单井和区域热流分析，恢复了北萨哈林盆地和鄂霍茨克海域各时期热流值的分布范围；对沉积盆地热演化各期次进行数值模拟，改进了简单沉降模型，使其适用于弧后拉分盆地；利用EASY%Ro 方法对热演化过程进行恢复，并与理论计算的热流值进行对比分析。研究表明，北萨哈林盆地各时期热流分布极为不均，热演化可以分成两个阶段：1） 古近纪，盆地内陆和海域具有各自的热流中心，其热演化过程相对独立；2） 晚渐新世后，盆地受弧后拉张和断裂剪切的共同作用，热流范围发生改变，构造拼合带成为新的热流中心。本文认为岩浆活动强弱和沉降速率差异是造成该现象的内因和外因。

| Abstract: | The North Sakhalin Basin is one of the most important petroliferous basins in the Fareast of Russia, and its heat flow research has great signification of the further exploration. Through the well and region heat flow analysis, we get the distribution of thermal area in the North Sakhalin Basin and the Okhotsk Sea at different periods. Then we simulate it’s responding thermal evolution and improve the traditional simple sedimentary formula. This improvement can expand the old model into the back-arc-shear basin. Besides that, through the comparison the heat flow distribution between the methodology of EASY%Ro and numerical simulation, we validate the reliable of simulation progress. The conclusion shows that the basin flow distribution is relative heterogeneous, and the evolution progress can be divided into two periods： 1） In Paleogene, the land region and sea areas have separate heat center and relatively independent heat evolution. 2） After Late Oligocene, effected by the interaction between back-arc extensional and the shear fracture, the heat flow distribution are becoming variable, and the heat flow center change to the flattened plate belt. We surmise the impact factors into two factors, the igneous activity and the sedimentary rate. |
