Abstract:

CO₂ emission which has a big impact on environment has caught global attentions. Air pollution and greenhouse effect are jeopardizing human being's environment. In 2009, the world economy steps into a downturn, but the climate change is still a core question for petroleum companies to concern, who are considering to carry out an environment-friendly policy to boost the economy. Using the abandoned oil reservoirs to bury CO₂ is regarded to be effective, which had been studied for a long time. This paper, based on a successful case of Dazhangtuo gas reservoir, analyzes the geology and economic advantages of using abandoned oil reservoirs in China, discusses how to choose the sites to bury CO₂, and presents some suggestions, hoping to provide theoretical and practical references for sustainable development and highlevel development of resources and environment.

Key words: abandoned oil reservoirs; CO₂ burying; choosing sites

摘要：

CO₂排放引发的环境问题引起国际社会高度关注，空气污染和温室效应正在严重地威胁着人类赖以生存的环境。2009年，尽管世界经济萎靡不振，但气候变化问题对国际石油公司仍是一个核心问题，国际大石油公司正在考虑实施环境友好的技术政策以刺激经济。利用废弃油气藏埋存CO₂是目前世界范围内认为比较有效并开始开展长期研究的方法之一。结合大张坨天然气储气库的成功实例，分析了废弃油藏作为地下储气库的地质及经济优势，依据我国CO₂排放区与主要油气区地理位置的耦合性特征，对全国范围内利用废弃油藏埋存CO₂的选址问题进行探讨，并提出建设性意见。希望能为资源和环境的高水平、高效益开发和可持续发展提供理论及实践依据。
