The current status and development prospects of CCUS-EOR technology development are sorted out from the perspective of ecological development. A good foundation is laid to promote the world low-carbon development pattern and the development of CCUS-EOR technology in oil-rich, low-permeability reservoirs. By analyzing the differences between China and the United States regarding the technology level, application scale, and production effect, the development gaps between different countries in terms of CO2 burial for enhanced oil and gas recovery are derived. In response to these gaps, recommendations for responsive technology research and supporting infrastructure construction are proposed, which are of reference significance for advancing the development of large-scale CCUS technology for all of humanity.

Population aging has become an important trend in the development of the global population structure, and high-quality elderly care has become a new problem faced by all human beings. Walkers can bring many conveniences to the lives of the elderly and provide a lot of support for the development of social elderly care. At present, the walkers on the market cannot help the elderly solve travel problems very well. Most of them ignore the psychological feelings of elderly users, and cannot meet the growing multi-dimensional and high-quality elderly life needs of the elderly. To this end, we designed an all-round intelligent follow-up walker; firstly, we obtained the basic data of user needs through user interviews and questionnaires. Design practice of azimuth-oriented intelligent follow-up walker, and finally verified the practicability of the walker through the physical model test. The all-round intelligent follow-up walker can meet the needs of users for daily community travel, walking assistance and storage. It has a high degree of integration of existing technologies and has a wide range of application prospects. The design of the runner provides a research and development idea.
