【摘要】 盐水层分布范围广,对CO2埋藏潜能大,将CO2注入深部盐水层进行埋存,已成为一种重要的减缓温室效应的途径。针对埋藏过程中如何准确预测CO2埋存容量这一重点和难点,简要论述深部盐水层CO2埋藏机理及适合进行CO2埋存的深部盐水层储层条件,重点介绍了几种深部盐水层CO2埋藏量的计算方法,并对比分析了不同方法对注入量的影响,提出适用于中国深部盐水层条件的CO2容量计算方法,为CO2在盐水层中埋藏的实际应用提供一定的参考和借鉴。更多还原

【Abstract】 Widely distributed saline aquifers in the world hold big CO2 storage potential.Injecting CO2 into deep saline aquifers for storage purpose has become an important approach to mitigate greenhouse effect.Accurate estimation of CO2 storage volume is a critical and difficult issue.This paper discusses the mechanism of CO2 storage in deep saline aquifer and the reservoir conditions suitable for CO2 storage.Several calculation methods of CO2 storage volume in deep saline aquifer are introduced;the influence of different injection methods on injection capacity is compared and analyzed;and a calculation method of CO2 storage volume for China’s deep saline aquifer is proposed.This research has certain reference significance to practical CO2 storage in saline aquifer.更多还原
