The Photovoltaic is one of the important development directions of new energy development, and its development is of great significance for optimizing the energy structure and achieving the goal of “double carbon”. With the rapid development of the green low-carbon circular development economic system in China, A oilfield has anchored the strategic goal of carbon peaking and carbon neutralization, and carried out the construction of photovoltaic power stations in accordance with the overall deployment of new energy of oilfield group company. According to the existing land resources of A oilfield, a water surface photovoltaic power station with an installed capacity of 6.95 mwp has been selected in the pit pond. After comprehensive comparison, the monocrystalline silicon module with high efficiency and low attenuation has been selected, and the specification of the battery module has been selected as 660 wp. The local solar energy resources have been fully utilized in the limited area. After completion, the average annual power generation of the photovoltaic power station is expected to reach 8.9185 million kwh, which can save 2724.6 tons of standard coal, reduce about 27.24 tons of soot emissions and 696 tons of carbon dioxide annually.28.78 tons, with good social and economic benefits. By exploring and analyzing the construction ideas related to the water surface photovoltaic project in oilfield A, this study provides a reference for other oilfields to carry out photovoltaic projects in the future, laying a solid foundation for the development of green oil fields.
