Based on the technological demands for significantly enhancing oil recovery and long-term CO2sequestration in the lacustrine oil reservoirs of China,this study systematically reviews the progress and practices of CO2flooding and storage technologies in recent years.It addresses the key technological needs and challenges faced in scaling up the application of CO2flooding and storage to mature,developed oil fields,and analyzes future development directions.During the pilot test phase(2006-2019),continuous development and application practices led to the establishment of the first-generation CO2flooding and storage technology system for lacustrine reservoirs.In the industrialization phase(since 2020),significant advances and insights have been achieved in terms of confined phase behavior,storage mechanisms,reservoir engineering,sweep control,engineering process and storage monitoring,enabling the maturation of the second-generation CO2flooding and storage theories and technologies to effectively support the demonstration projects of Carbon Capture,Utilization and Storage(CCUS).To overcome key technical issues such as low miscibility,difficulty in gas channeling control,high process requirements,limited application scenarios,and coordination challenges in CO2flooding and storage,and to support the large-scale application of CCUS,it is necessary to strengthen research on key technologies for establishing the third-generation CO2flooding and storage technological system incorporating miscibility enhancement and transformation,comprehensive regulation for sweep enhancement,whole-process engineering techniques and equipment,long-term storage monitoring safety,and synergistic optimization of flooding and storage. 展开更多

By reviewing the development history of stimulation techniques for deep/ultra-deep oil and gas reservoirs,the new progress in this field in China and abroad has been summed up,including deeper understanding on formation mechanisms of fracture network in deep/ultra-deep oil and gas reservoir,performance improvement of fracturing fluid materials,fine stratification of ultra-deep vertical wells,and mature staged multi-cluster fracturing technique for ultra-deep and highly deviated wells/horizontal wells.In light of the exploration and development trend of ultra-deep oil and gas reservoirs in China,the requirements and technical difficulties in ultra-deep oil and gas reservoir stimulation are discussed:(1)The research and application of integrated geological engineering technology is difficult.(2)The requirements on fracturing materials for stimulation are high.(3)It is difficult to further improve the production in vertical profile of the ultra-deep and hugely thick reservoirs.(4)The requirements on tools and supporting high-pressure equipment on the ground for stimulation are high.(5)It is difficult to achieve efficient stimulation of ultra-deep,high-temperature and high-pressure wells.(6)It is difficult to monitor directly the reservoir stimulation and evaluate the stimulation effect accurately after stimulation.In line with the complex geological characteristics of ultra-deep oil and gas reservoirs in China,seven technical development directions are proposed:(1)To establish systematic new techniques for basic research and evaluation experiments;(2)to strengthen geological research and improve the operational mechanism of integrating geological research and engineering operation;(3)to develop high-efficiency fracturing materials for ultra-deep reservoirs;(4)to research separated layer fracturing technology for ultra-deep and hugely thick reservoirs;(5)to explore fracture-control stimulation technology for ultra-deep horizontal well;(6)to develop direct monitoring technology for hydraulic fractures in ultra-deep oil and gas reservoirs;(7)to develop downhole fracturing tools with high temperature and high pressure tolerance and supporting wellhead equipment able to withstand high pressure. 展开更多

According to the specific requirements and actual conditions of industrial development at this stage, in-depth research and exploration on its development direction and decision-making from the perspective of economics will have great help to the potential development capability of the industry. It can achieve the scientific and effective development goal step by step. And it can suit the changing development form at this stage, and effectively reduce the problems generated by enterprises under actual conditions. Therefore, when the research content related to the industry is refined, we must stand in the perspective of economics at an early stage. Fully consider its corresponding development direction and various decisions. And then we can effectively expand the development ideas of the enterprise, and can make the enterprise scale and overall development level be expanded and improved. Industry development with the accumulation of time, more and more experience in practice, can effectively reduce the scope of influence of related issues. Therefore, from the perspective of industrial economics, this paper analyzes and studies the development direction and decision-making of the industry. It also provides a reference for the future scholars in this research area, so that the development effect of the industry in the future practice can be better. 展开更多

Automation technology can help the mechanical manufacturing industry to better optimize the production operation, and can also save a lot of manpower and material resources. In the production process, it can also improve the production efficiency of products by combining with relevant advanced technologies, such as computer technology. Especially in the future development, people's requirements for products are getting higher and higher. If relevant enterprises cannot create appropriate products according to people's requirements, they will inevitably be eliminated by the times. However, the integration of automation technology into mechanical manufacturing can well meet the development needs in the future. On the premise of ensuring product quality, cost can be saved and production efficiency can be improved. 展开更多
