Daqing Oilfield was renamed. As early as the oil battle in the 1960s, Daqing Oilfield was always called Daqing Petroleum Administration Bureau. When China Petroleum was restructured from 65438 to 0999, the surviving part was still called Daqing Petroleum Administration Bureau, and the listed part was changed to Daqing Oilfield Limited Liability Company. In 2008, China Petroleum Group Company further reformed, and the surviving enterprises merged with listed enterprises, and Daqing Oilfield was changed to Daqing Oilfield Limited Liability Company.
