"双碳"战略下我国能源管材技术进展及机遇与挑战OA

Against the backdrop of the dual-carbon policy driving the energy structure toward a green and low-carbon transition,the transformation and upgrading of the oil and gas industry have put forward stringent requirements for the service performance of oil and gas pipeline materials and equipment.Focusing on the dual-carbon development strategy and energy development trends,this paper systematically reviews the cutting-edge progress of two core pipe material systems:pipes for clean and green energy transmission(natural gas,hydrogen,CO2,compressed/liquefied air energy storage)and pipes for extreme downhole oil and gas field development(unconventional oil and gas development,CCUS,underground coal carbonization and gasification).In view of the service characteristics of various pipes and the related failure mechanisms such as hydrogen embrittlement and corrosion,this paper sorts out the core technical strategies in terms of composition design,microstructure regulation,and manufacturing processes.It also highlights representative domestic R&D progress,including L360MH hydrogen transmission pipes,CT150 ultra-high-strength coiled tubing,and L450M pipes for supercritical CO2 transmission.Combined with the direction of oil and gas development,this paper points out the future development directions and research priorities of the corresponding pipe materials.Finally,based on the technical demands of energy development,this paper suggests that future key research directions should focus on core fields of advanced manufacturing technologies,such as key materials for hydrogen energy storage and transportation,diversified energy storage and thermal management,and rapid repair of oil pipelines via additive manufacturing.It is intended to provide technical references for China's energy transition and the technological development system of high-performance oil and gas pipe materials.
