摘要
在我国“双碳”战略目标下,海上碳捕集、利用与封存(CCUS)技术已成为实现深度碳减排的关键路径。为推进该技术的规模化、集群化发展,我国已在“十四五”期间布局千万吨级海上CCUS集群项目。然而,传统海上笼统注气技术存在注入效率低、调控精度不足等问题,严重制约了CCUS项目的规模化发展。针对这一挑战,通过进行材料选型、结构设计、有限元仿真及室内测试,研制了一种具备8挡精准调控功能的液控智能注气调控阀。地面试验表明,该调控阀在模拟CCUS井极端工况(150℃、70 MPa)下表现优异,其成果为千万吨级海上CCUS集群项目的安全高效运行提供了关键技术支撑。
Under China’s“Dual Carbon”strategic goals,offshore carbon capture,utilization,and storage(CCUS)technology has become a critical pathway for achieving deep carbon emission reductions.To promote large-scale and clustered development of this technology,China has launched the layout of 10-million-ton-scale offshore CCUS projects during the“14th Five-Year Plan”period.However,traditional offshore blanket gas injection technology suffers from low injection efficiency and insufficient control precision,severely limiting the large-scale deployment of CCUS projects.To address this challenge,this study developed a hydraulically controlled intelligent gas injection valve with an 8-gear precision control function through material selection,structural design,finite element simulation,and laboratory testing.Ground tests demonstrate that the control valve exhibits excellent reliability under simulated extreme CCUS well conditions(150°C,70 MPa).This achievement provides key technical support for the safe and efficient operation of 10-million-ton-scale offshore CCUS projects.
