The largest and longest supercritical carbon dioxide transmission pipeline in Jiangsu Province has been put into operation. The inlet pressure is 8.5 megapascals, the injection pressure is 25.5 megapascals, and the equipment is operating stably. "On May 19, Tang Yulong from the Taizhou Oil Production Plant of Sinopec East China Oil and Gas Branch reported to the production control center on the operation status of the carbon dioxide flooding project at Well Qu 1-20. This significant milestone marks the official commissioning of the largest and longest supercritical carbon dioxide pipeline in Jiangsu Province – the project connecting the East China Petroleum Bureau’s CCUS peak-shaving center to the Zhangjiaduo Oil Field (Phase I). This 42-kilometer-long pipeline sets a precedent in Jiangsu Province, and it is of great significance for oil fields to increase production and recovery rates through carbon dioxide injection, as well as for achieving the sequestration of carbon dioxide. Technologically, this pipeline makes innovative use of advanced techniques such as direct pressurization via carbon dioxide injection skids; it fully leverages the integrated carbon industry chain advantages of the East China Petroleum Bureau in areas such as carbon dioxide capture, transportation, oil displacement, and sequestration. Its designed annual transport capacity is 230,000 tons, which is equivalent to the amount of carbon absorbed by about 10 million trees in one year. By transporting the captured carbon dioxide to the oil fields in the Subei industrial area for storage and recharging, a \"win-win\" situation was achieved, with both carbon emission reduction and increased crude oil production. This project is an important outcome of the East China Petroleum Bureau’s active response to the **\"dual carbon\" strategy and its efforts to promote the transition to clean energy. Looking to the future, the East China Petroleum Bureau also plans to actively advance the construction of the second phase of the carbon dioxide long-distance pipeline project. Once the second phase of the project is completed, it will become the core carbon network for carbon emission and utilization enterprises in Jiangsu Province. It will not only play a significant role in promoting the green and low-carbon transformation of enterprises in this region but also contribute greatly to the vigorous development of China’s carbon dioxide capture, utilization, and storage (CCUS) industry.
