摘要
化石燃料作为目前人类主体能源,其地位在短期内难以改变,但"双碳"目标的提出为我国产业结构升级和能源安全带来了新挑战与机遇.二氧化碳地质封存技术(CCS)是一种十分有效的减排手段,也是实现"双碳"战略的重要途径.该技术将工业活动中所收集的CO2进行特殊处理后,灌注进入封闭且稳定的地层中,从而降低CO2排放量,减缓大气污染与温室效应.目前,CCS技术已经受到国内外研究学者的广泛关注,中国的CO2减排形势非常严峻,因此对二氧化碳地质封存技术的研究尤为迫切.为了更好地促进对该技术的认识和研究,本文拟从咸水层封存、废弃油气藏封存、深部不可开采煤层封存和玄武岩矿化封存4个方面对国内外的研究现状进行综述,并提出了当前研究中的不足和需要进一步研究的问题.
Abstract
The position of fossil fuels as the most important energy for human beings is difficult to change in the short term,but the proposal of the "dual carbon" goal has brought new challenges and opportunities for China's industrial structure upgrading and energy security.Carbon emission reduction technology represented by CO2 underground storage is an important way to achieve the " dual carbon" strategy.Carbon dioxide geological sequestration technology (CCS) is regarded as a direct and effective means of emission reduction.This technology is to capture the CO2 originally discharged into the atmosphere and inject it into the closed underground reservoir after treatment,to reduce the emission of CO2 into the atmosphere and slow down the atmospheric pollution and greenhouse effect.At present,CCS technology has been widely concerned by researchers domestic and overseas.The situation of CO2 emission reduction in China is very serious,thus,the study of CO2 geological sequestration is particularly urgent.To carry out further research,this paper reviews the global research status from four aspects:saline aquifer storage,abandoned oil and gas reservoir storage,deep unexploitable coal seam storage,and basalt storage.In addition,the deficiencies in the current research and the problems that need further research are also presented.
