Co2 Injection Speed Increase in Xinjiang Oilfield

Co2 Injection Speed Increase in Xinjiang Oilfield

As of March 28, the amount of carbon dioxide injected into Xinjiang oil fields this year exceeded 100,000 tons. Compared to the same period last year, the daily injection rate increased by about 154%.

Since the beginning of this year, Xinjiang Oilfield has taken the lead of "carbon seeking green new momentum, driving low-carbon large oil fields", innovatively applied the "three pipes to" operation mode, and fully ensured the efficient operation of 11 CCUS carbon injection test areas.

Full chain tracking management in place. The CCUS project Management Department of Xinjiang Oilfield Development Company opens up the whole industrial chain process of carbon purchase, carbon transport and carbon injection, implements the whole-chain closed-loop management, and ensures the all-weather and efficient operation of CCUS project. Site injection management in place. Xinjiang Oilfield design and build standardized system, standardized well site layout, standardized safety management, standardized equipment parameters "four standardized" well sites. At present, 74 sets of CO2 injection equipment have been "settled" at the production site. In addition, the oilfield has set up a dynamic tracking management mechanism for injection Wells to track the on-site injection situation in real time, optimize and adjust injection and production parameters in time, and ensure the injection of carbon dioxide and the displacement of crude oil. Operation safety supervision in place. In accordance with the requirements of total factor management, project managers build a small CCUS business system, and establish skid mounted injection standards and specifications to guide the safe and orderly development of CCUS projects by combing through the whole chain business process, analyzing process safety and identifying risk lists ⒅.

At present, the daily carbon injection volume of 11 CCUS carbon injection test areas in Xinjiang oilfield has reached more than 1,500 tons, an increase of 910 tons over the same period last year. Among them, the carbon dioxide miscible flooding test of Baikouquan reservoir in Bai21 well area is the key project of the "ballast stone" project of the Group company, and the daily carbon injection volume of 6 injection Wells is up to 210 tons.
