基于有机成熟作用理论, 应用改进的Karweil方法, 以塔里木盆地塔中地区某些钻孔为实例, 提出了应用沥青反射率推算油气生成与运移地质时代的原理与方法. 应用该方法推算出塔中地区古生代地层中3组沥青形成地质时代分别是中-晚奥陶世、晚白垩世～早第三纪及晚第三纪, 反映该区在这3个地质时期存在油气生成与运移. 为沥青的地质应用提供了新的思路. Based on the theory of organic maturity and applying the improved Karweil method, taking some boreholes in the Tazhong area of ​​Tarim Basin as an example, the principles and methods of calculating the geologic times of hydrocarbon generation and migration using asphalt reflectivity are proposed. By using this method, In the Paleozoic strata, three groups of bitumen formation geologic times are Meso-Late Ordovician, Late Cretaceous ~ Early Tertiary and Late Tertiary, respectively, reflecting the hydrocarbon generation and migration in these three geological periods. It provides a new idea for the geological application of asphalt.
