摘      要：This paper systematically presents the established technologies and field applications with respect to research and engineering practice of CO_(2) capture,enhanced oil recovery(EOR),and storage technology in Jilin Oilfield,NE China,and depicts the available series of supporting technologies across the industry *** simulation calculation+pilot test+field application,the adaptability of the technology for capturing CO_(2) with different concentrations in oilfields was *** low energy-consumption,activated N-methyl diethanolamine(MDEA)decarburization technology based on a new activator was developed,and the operation mode of CO_(2) gas-phase transportation through trunk pipeline network,supercritical injection at wellhead,and produced gas-liquid separated transportation was *** to different gas source conditions,liquid,supercritical phase,high-pressure dense phase pressurization technologies and facilities were applied to form the downhole injection processes(***-tight tubing and coiled tubing)and supporting anti-corrosion and anti-blocking *** the practice of oil displacement,the oil recovery technologies(*** water-alternating-gas injection,CO_(2) foam flooding,and high gas-oil ratio CO_(2) flooding)and produced fluid processing technologies were *** numerical simulation and field tests,three kinds of CO_(2) cyclic injection technologies(*** injection,injection after separation and purification,and hybrid injection)were formed,and a 10×10^(4) m^(3)/d cyclic injection station was constructed to achievezero emissionof associated *** CO_(2) storage safety monitoring technology of carbon flux,fluid composition and carbon isotopic composition was *** whole-process anti-corrosion technology with anticorrosive agents supplemented by anticorrosive materials was *** integrated demonstration area of CO_(2) capture,flooding and storage with high efficiency and low energy-consu
