Abstract: The petroleum industry new faces the demand for green and low-carbon transition thanks to global energy structural transition and China’s“ dual carbon” goals. This article analyzes the current development conditions of Daqing Oilfield in the areas of new energy construction, technological challenges, variable-conditioning production technology and distributed energy supply system. A remarkable growth is brought about in new energy installed capacity and productivity. However, there are still a series of technological and economic challenges, such as instability of new energy fueled electricity and high cost of energy storing technology. Daqing Oilfield has continued its efforts to strengthen technological innovation and system optimization, based on green electricity integration technology for mechanical oil production wells, electric heating for wax elimination and prevention by means of green electricity, and integration of green electricity for water injection according to variable conditions. Daqing Oilfield established the distributed energy supply system compatible with the re-engineering system, thus effectively raising the capacity for new energy consumption and absorption. This also solved the problems of connecting new energy to the power grid and brought about high-efficiency utilization of new energy and stable operation of the oilfield production system, facilitating in-depth integration of green electricity with oilfield production.

Key words: Daqing Oilfield; green electricity integration; operational technology for variable conditions; distributed energy supply system; green and low-carbon transition; electric heating for wax elimination and prevention
