摘要
CO2的捕获与地质埋存是解决碳排放、减少大气污染和全球气候变化的有效途径之一。近年来,许多国家包括中国都相继在这方面进行了大量的研究和试验。文中介绍了国内外CO2埋存的技术现状和开展研究项目的概况,尤其是我国在这一领域开展的工作。重点总结分析了CO2的捕获与地质埋存的意义、方法和技术,对于CO2注入后的运移监测手段和原理进行了较为详细的阐述。详细分析和讨论了CO2注入煤层后,对煤层及其围岩产生的压力、孔隙、电阻率变化以及与原有孔隙中液体产生的各种相互作用,指出了煤层注入CO2后可采用的运移监测方法。
CO2 capture and geological storage is one of available methods for solving carbon emission and lessening atmosphere pollution and world climate change.In recent years,many countries and China have made a large amount of research and test.The technique situations and research works developed for CO2 capture in domestic and abroad are introduced in the paper,especially works developing in China.The significance and method as well as technique of CO2 capture and geological storage are stress summarized and analyzed,and the movement monitoring means and principle after injecting CO2 is described in detailed.It is importantly analyzed and discussed that effects on pressure and pore and resistivity change of coal bed and surrounding formation as well as mutual reactions between liquids in original pore,the available monitoring methods are proposed for CO2 movement,after injecting CO2 into coal bed.
