摘要

燃煤电厂烟气CO2捕集驱油封存技术是提高特低渗透油藏采收率和减少温室气体排放的有效方法。针对燃煤电厂CO2捕集和大幅度提高低渗透油藏采收率的技术瓶颈开展研究,形成了燃煤电厂烟气CO2捕集纯化处理技术、CO2驱提高采收率油藏适应性评价体系、室内实验技术和油藏工程优化设计技术系列,配套了CO2驱注采工艺和地面工程技术系列,并建成国内外首个燃煤电厂烟气CO2捕集与驱油示范工程。实践表明,技术应用效果良好,开发的高效CO2捕集溶剂及工艺比传统单乙醇胺(MEA)工艺捕集成本降低35%,CO2驱油与封存示范区累计注入CO2 12.8万t,累计增油2.9万t,封存CO2 11万t。

Abstract

The carbon dioxide capture, the flooding and the storage technologies in a coal-fired power plant are effective for enhancing the oil recovery in an ultra-low permeability reservoir and reducing the greenhouse gas emissions. The studies in these directions provide insight on the dynamic microscopic mechanism of the carbon dioxide mixed with oil, the capture of the carbon dioxide to reduce the high cost of coal-fired power plants, the serious corrosion of oil storage and production systems and other key technologies, to form the technology series, including the carbon capture coal-fired power plant flue gas purification technology, the carbon dioxide EOR reservoir adaptability evaluation system, the indoor experimental techniques and the reservoir engineering optimization design technology, supported with the carbon dioxide flooding processes and the ground engineering. The first demonstration project of the coal-fired power plant carbon capture, flooding and storage is established, with good results. Compared with the conventional MEA capture process, the efficient carbon capture solvents and the process make a cost reduction of 35%, over 128000 t of CO2 being successfully injected into the reservoir, with the cumulative oil increment of 2.9×104 t,and 110000 t of CO2 being stored in the CO2 flooding and sequestration demonstration zone.
