China's petroleum enterprises have taken an active part in international cooperative oil and gas projects in recent years.Geological storage and utilization of carbon dioxide(CO2)is a key technology to solve greenhouse gas emission and fulfill the"carbon peak and carbon neutrality"objective.From the angles of the CCS/CCUS service classification and the CO2 sources,this article analyzes the offshore CCS/CCUS projects worldwide and summarizes four types of offshore CCS/CCUS service model.Based on the factors like the CO2 phase variation and impurity content,the article studies the influence of CO2 functions and analyzes the bottlenecks in matching of offshore CO2 sources,transportation and injection.Taking into account the present conditions and development demands of domestic offshore CCS/CCUS business,it clarifies the future orientations for offshore CCS/CCUS service technological development in three areas--the model for matching source sink in the form of offshore CO2 cluster and hub,optimization of injection model and systematic equipment R&D,and the ability for flow-keeping technology.
