摘　　要：为监测二氧化碳地质封存状态、评估封存效果,在钻井过程中对各个地层烃类和二氧化碳含量及碳同位素进行测量。检测结果表明,钻井液气碳同位素的纵向变化与油气藏储盖组合的划分具有一定的相关性,可为二氧化碳封存圈闭密封性评价提供依据,二氧化碳封存后可对盖层的封闭性评价及二氧化碳封存状态进行监测。To monitor the status of carbon dioxide geological sequestration and evaluate its effectiveness,hydrocarbon and carbon dioxide content,as well as carbon isotope measurements,are conducted in various formations during the drilling process.The results indicate that the vertical variation of carbon isotopes in drilling mud gas correlates with the division of reservoir-cap rock assemblage in oil and gas reservoir,which can provide a basis for evaluating the sealing integrity of carbon dioxide sequestration traps.After carbon dioxide sequestration,the sealing integrity of cap rock and the monitoring of carbon dioxide sequestration state can be conducted.
