| 摘 要： | 沉积盆地深部存在体积巨大的咸含水层，是很好的埋存CO2的地质储体。可靠合理的估计CO2储存容量是选择场址的重要前提。目前国际上较为通用的评价CO2储存容量是金字塔评价方法。松辽盆地咸含水层岩性以白垩系的嫩江组砂岩和青山口组砂岩为主，空隙发育较好，盖层连续完整且封闭良好，决定了其可以作为储存CO2的地质储体。以松辽盆地为实例，估算了咸含水层CO2理论储存容量大约为6916Gt。

| Abstract: | The huge deep saline aquifer buried in Songliao sedimentary basin is a one of good geological media for CO2 geological storage. Reliable and reasonable estimation of CO2 storage capacity is an important factor for site selection and development. The universal pyramid method is introduced to assess the CO2 storage capacity for the sedimentary basin. The deep saline aquifer of Songliao basin is mainly made up of Cretaceous Nenjiang Group sandstone and Qingshankou Group sandstone. The saline aquifer has well developed porosity and the continuous sealing trap is overlying it. All of these determine that it can be used to CO2 storage. The pyramid method is applied to the deep saline aquifer of Songliao basin and the effective storage capacity of CO2 is about 6916Gt. |
