China's First Large-Scale Carbon Dioxide Transmission Pipeline

China's first large-scale carbon dioxide transmission pipeline is fully connected, taking a solid step towards climate change

Recently, according to Sinopec News, China's first large-scale carbon dioxide transmission pipeline - Qilu Petrochemical Shengli Oilfield million-ton CCUS demonstration project carbon dioxide transmission pipeline has been fully connected. This is a significant project, which is expected to be put into operation in May this year. It can transport more than 1 million tons of carbon dioxide captured by Qilu Petrochemical No. 2 Fertilizer Plant to the underground oil reservoir of Shengli Oilfield for oil flooding and storage.

Carbon dioxide flooding technology is a technology to enhance oil recovery and reduce CO2 emissions. This technology injects a large amount of carbon dioxide gas into the underground oil reservoir, which can change the pressure and material balance of the underground oil reservoir, so that the originally unrecoverable residual oil can be fluidized, thereby improving the recovery rate of the underground oil reservoir. Transporting the carbon dioxide captured by Qilu Petrochemical to the underground reservoir of Shengli Oilfield for oil flooding and storage can not only improve the recovery rate, but also reduce carbon dioxide emissions.

At present, China is the third largest oil producer in the world, but due to reasons such as aging oil fields and increasing difficulty in oil recovery, the domestic oil recovery rate is generally low. The application of carbon dioxide flooding technology can enhance oil recovery and increase oil reserves, thereby providing new development opportunities for China's oil industry. According to statistics, the implementation of carbon dioxide flooding technology can fluidize the originally unrecoverable residual oil, thereby increasing the recovery rate by 5% to 30%, and increasing the oil reserve by 10% to 20%.

In addition, the construction of the project will also help the development of China's environmental protection. Today, global greenhouse gas emissions are seriously exceeding the standard, and carbon dioxide is one of the main greenhouse gases. Carbon dioxide flooding technology will reduce the environmental pollution of carbon dioxide through the sequestration of carbon dioxide, achieve a win-win situation of environmental protection and economic benefits, and form a synergy in sustainable development and sustainable development.

The impact of this pipeline project is not limited to oil exploration and environmental protection, but will also play a positive role in promoting the development of related industries. For example, the construction of this project requires a lot of support from pipeline transportation, manufacturing and environmental protection markets, which will directly promote the upgrading and development of related industries. According to analysis, the completed pipeline can provide sufficient carbon dioxide resources for industrial production such as Sinopec, steel and cement in the future, thereby promoting the development of industrial production, which is of great economic significance.

In addition, the implementation of the project will also contribute to the national energy strategy and low-carbon development. China has written the goals of "carbon peak" and "carbon neutrality" into the "14th Five-Year Plan". These goals require a lot of technical and action support. Carbon dioxide flooding technology is an effective emission reduction technology. By injecting carbon dioxide into underground oil reservoirs, it can reduce the release of carbon dioxide in the atmosphere and achieve the effect of emission reduction. The implementation of this project will provide China with a broader space and opportunities for the development of low-carbon fields, and at the same time declare to the world China's determination and actions in dealing with climate change, and it will play an important role in the implementation of China's economic development and green development strategy. is also of great significance.
