摘要: 充分利用包裹体的岩相学特征、均一温度特征、气体组分特征以及碳同位素特征等,对松辽盆地南部长岭断陷二氧化碳气藏的成藏期次进行了分析。长岭断陷二氧化碳气藏包裹体温度为160~170℃,均超过该区古地温,推断此为热流事件所造成的。通过对松辽盆地大地构造环境及其他分析,综合认为长岭断陷二氧化碳气藏主要形成于中生代末期至新生代,应为晚期成藏。

Abstract: The CO2 reservoir-forming periods in Changling fault depression of southern Songliao Basin is analyzed, by fully using the lithofacies characteristics, characteristics of homogenization temperature, gas composition and carbon isotope characteristics of inclusions. The temperature of the inclusions of the CO2 reservoir in the fault depression ranges from 160℃ to 170℃, higher than the palaeogeothermal of the area, which is inferred to be caused by heat events. Through the analysis of the tectonic environment of the basin, it is considered that the CO2 reservoirs in Changling fault depression mainly developed from late Mesozoic to Cenozoic, which should be late reservoir formation

Key words: Songliao Basin, Changling fault depression, fluid inclusion, reservoir-forming period, CO2 reservoir
