Under global climatic crisis and China's"carbon peak and carbon neutrality"goals,the oilfield enterprises accelerated development towards green transformation to promote low-carbon oil and gas production.Fossil fuels accounted for more than 70 percent of energy consumed for oilfield oil and gas production.Solar-thermal application was the main direction in clean thermal power at oilfields.This paper compares the various characteristics of active solar thermal collection technology in the solar thermal industrialized application field and analyzes the temperature demands for the various oilfield thermal application environments,concluding that the diversity of solar-thermal technology is highly matched with the diversity of oilfield thermal energy application demands.Elaborating the various environments for oilfield thermal energy consumption,the paper also analyzes multi-element technological pathways,such as single-well oil extracting cogeneration,high-efficiency solar-thermal replacement on a small scale,interconnection and sharing of a large-scale solar-thermal system,and solar-thermal gradient application under the complicated thermal energy consuming environment.Focusing on the bottlenecks for solar-thermal application at oilfields,it comes up with the application pathways in such areas as selection of projects,determination of scales,design of system,optimization of synergy and energy regulation.As for formulation of the oilfield solar-thermal application plan,determination of the order for gradual clean replacement according to the local conditions holds the key to improving performance of replacement.Systematic mindset based on both upstream and downstream businesses and optimization of operational strategy are the preconditions for optimization of the design scheme.Rigorous comparability and estimation of the service life period are the basis for selection from a number of plans.The study and practice of the various thermal consuming environments are the important pathways for improving the quality of plans.It is proposed that oilfield enterprises should gradually improve their understanding in the practice,sustainably optimize the thermal energy application plans,accelerate execution of the plans and further promote oil and gas development in harmony with new energy.
