This study has constructed a brand-new clean and low-carbon production mode and established an oilfield as the first carbon-neutral factory for oil and gas production in China targeting Scope 1 and 2 greenhouse gas emissions. To achieve zero carbon emissions in oil and gas field enterprises through energy conservation and emission reduction measures in the production and manufacturing process is an important goal of the current transformation and development. This study systematically creates a method through energy consumption sorting, carbon verification, clean resource analysis, process energy saving optimization, scheme comparison and economic evaluation in planning layout, and implementation process of carbon-neutral factories construction. According to this method, this study sorts and optimizes the energy consumption of the central processing facility in the operation area. It utilizes solar energy, newly installs equipment such as photovoltaic module, heat pump, electromagnetic heater, and covers all the production needs with green electricity. Finally, it completely replaces the associated gas, and successfully builds carbon-neutral and achieves certification from authoritative institutions.
