Under the background of"dual carbon"goal,Daqing Oilfield spares no efforts to construct the clean high-efficiency energy system and the million-kilowatt new energy base.Taking into account super-high water-cut development and typical characteristics of a complete oilfield,Lamadian Oilfield tried to construct the Labei northern block low carbon demonstration zone on the basis of the resource advantages.Based on a comprehensive energy survey,the oilfield clearly identified gray electricity and natural gas as the targets for replacement and came up with the two-step construction principle of"energy saving for carbon reduction and keeping clean for carbon replacement".Combined with the heat-using characteristics,the oilfield made an overall plan for residual heat,geothermal heat,solar heat and electrical hear reciprocating with other energy in the efforts for re-creation of the technical process,stereoscopic energy efficiency,replacement by clean heat energy,and replacement by clean electrical energy.Based on such characteristics as high intensity of pipeline networks in the central part of the oilfield and a large quantity of land available for use in the surrounding area,the oilfield was targeted at maximum power generation and minimum abandoned power and optimized distribution and scale of wind and solar electricity generation,thus bringing about regional multi-energy reciprocation,balance between energy supply and consumption and high replacement rate.The low carbon demonstration zone can make an in-depth integration of new energy technology with the existing production technical process,launching the pilot study of energy storage,hydrogeneration,micro power grid,and energy regulation technology.Construction of the low carbon demonstration zone is expected to completed in 2025 when the clean energy replacement rate will reach 46.4 percent,effectively accelerating the oilfield's energy transformation and green low-carbon transition.
