摘要: 利用动力学实验,恢复了鄂尔多斯盆地上古生界煤系镜质体反射率Ro热演化史,并将其与相邻层位砂岩中包裹体的均一温度进行了对比.结果显示,Ro所反映的最大古地温高于地层中包裹体的均一温度.即在地层达到最大古地温之前,地层中的水—岩相互作用已经停止,即气、水界面已经迁移,天然气已经成藏.由此可知,鄂尔多斯盆地上古生界煤成气在早白垩纪末达到最大生烃量以前已经完成了气、液的完全置换,煤成气的气源条件充足.

Abstract: The vitrinite reflectance revolution of the Upper Paleozoic of Ordos Basin was restored with kinetics experiment,and the maximum palaeo-temperature from vitrinite reflectance was compared with the homogenization temperature of fluid inclusion.The results show that the maximum palaeo-temperature from vitrinite reflectance is higher than the homogenization temperature of fluid inclusion in the middle and the east of Ordos Basin,and the two is similar in the north of the basin.These results suggest that the hydro-gas boundary had migrated out of the strata in the middle and the east of the basin before the period of the maximum temperature and the Upper Paleozoic gas pool were formed.Meanwhile the hydro-gas boundary had not transferred out of the strata and the formed gas could not driven the water out in the north of the basin.

Key words: vitrinite reflectance, fluid inclusion, homogenization temperature, gas pool, gas-water boundary, migration, Ordos basin
