| 摘 要： | 实施CO2地质封存是目前公认的减少温室气体排放的有效方法。在可能进行封存的场所中，咸水含水层封存潜力最大，机理也最为复杂。其中毛细残余封存机理在封存量和封存安全性方面均具有十分重要的意义。在评价毛细残余封存量时，残余气饱和度是一个十分重要的参数。文中提出了测定残余气饱和度的实验方法，并实际应用于中国塔里木盆地奥陶系礁灰... |

| Abstract: | The geological storage of CO2 is widely accepted as an effective method to reduce the release of greenhouse gases to the atmosphere.Saline aquifer has the most sequestration potential and the most complicated mechanisms among all the sites that could implement CO2 geological sequestration.Of all the mechanisms,residual gas sequestration has the extremely vital significance in respect of storage capacity and security,and residual gas saturation is a key parameter to calculate the capacity.In this study,an experimental method applied to a rock sample taken from Ordovician reef limestone of Tarim Basin was used to measure the residual gas saturation.Through simulating water flooding supercritical CO2 saturated core under 40 ℃ strata temperature,8 MPa strata pressure,the pressure and flux change with time were observed during the course,and residual gas saturation was measured as 0.368.Before the flooding experiment,sample porosity and permeability coefficient were measured as 2.83% and 5.56×10-9 m/s,respectively,by saturated weighing and permeating experiments. |
