摘　　要：碳捕集、利用与封存(CCUS)是实现“双碳”目标的重要技术手段,涵盖捕集—输送—注入—采出—回注等关键环节。胜利油田经过多年探索和攻关,形成了输注采系列关键工程技术。针对压损温差带来的CO_(2)相变与长距离泄漏风险,建立了基于相态控制的长距离CO_(2)管道安全输送工艺技术,实现高效经济输送;研发了中国首台套管道输送泵;建成了中国最长的超临界压力CO_(2)长输管道,补齐了国内CO_(2)长距离输送的短板。为满足示范工程大排量CO_(2)高压注入的需要,研发了国内首台套高压密相注入泵,实现了40 MPa高压密闭注入;针对注气压力高、气液比高、泵效低以及CO_(2)腐蚀等问题,形成了免压井安全注气管柱、多功能采油管柱、CO_(2)驱腐蚀防护等注采配套工程工艺技术,实现了高效安全注采和长效腐蚀防护。建成了中国首个集管输工程、注入装备、驱油封存、注采工艺、集输回注为一体的,多领域、多节点的百万吨级CCUS示范工程,目前各环节运行良好,实现“平稳、安全、高效、绿色”运行。对胜利油田百万吨级CCUS输注采工艺及配套装备进行了总结,以期为后续CCUS工程建设提供借鉴和指导。CCUS technology is a crucial technology for achieving the goal of“dual carbon”,involving process such as capture,transportation,injection,extraction and re-injection.Shengli Oilfield has developed essential engineering technologies for transportation and injection through years of exploration.To manage the phase changes of CO_(2) and the risks of long-distance leakage due to pressure loss and temperature variations,a safety transportation technology for long-distance CO_(2) pipelines was established.This technology is based on phase state control,ensuring efficient and cost-effective transportation.developed China’s first casing pipeline transport pump;and built China’s longest long-distance supercritical pressure CO_(2) pipeline,which makes up for the shortcomings of the long-distance CO_(2) transport in China.In order to meet the needs of high-pressure injection of largedisplacement CO_(2) in the demonstration project,China’s first high-pressure dense-phase injection pump has been developed,realizing high-pressure dense-phase injection of 40 MPa.In view of the problems of high injection pressure,high gas-to-liquid ratio,low pumping efficiency,and corrosion of CO_(2),the engineering process technology of injection and extraction supporting such as safe injection of gas pipeline columns for pressure-free wells,multi-functional oil recovery pipeline columns,and corrosion prevention of CO_(2) repulsion has been formed to realize high-efficiency,safe injection and extraction and long-lasting corrosion protection.China's first multi-field,multi-node,one-million-ton CCUS demonstration project integrating pipeline transport engineering,injection equipment,flooding and sequestration,injection-extraction process,and gathering-transmission and re-injection,has been operating well and realizing“smooth,safe,efficient and green”operation in all aspects.This summary of the one-million-ton CCUS transportation-injection-extraction process and supporting equipment in Shengli Oilfield is intended to provide referenc
