| 摘 要： | 塔里木盆地库车坳陷大宛1井和克参1井的烷烃气出现负碳同位素系列,其根本原因是天然气的散失分馏所致,同时由于该区烃源岩的成熟度处于高熟或过熟阶段(R_o=1.18％～1.77％),并非无机成因。

| Abstract: | The key factor to existing negative carbon isotope anomaly m paraffin hydrocarbon gas from Dawan-1 and Kecan-1 wells in Kuche depression of Tarim Basin, is resulted from the evaporation and distillation of natural gas. Another reason is due to the high or post maturation of source rocks in the area. |
