Application of Complementary Multi-energy Distributed Energy System in Oil Transfer Station

Oilfield companies with oil and gas as their main products are not only large energy producers, but also large energy consumption and carbon emission producers. Large application of efficient, clean and low-carbon energy is an effective way for oilfield companies to achieve carbon peaks and ultimately achieve carbon neutrality goals. The oil and gas gathering and transportation system is the main body of the oilfield ground engineering. The oil transfer station is an important link in the oil and gas gathering and transportation system. It is mainly responsible for the heating and pressurization of crude oil in the process of crude oil transportation. The existing energy supply system is powered by grid electricity and natural gas boilers to meet the electrical load and low temperature heat load requirements respectively. The complementary multi-energy distributed energy system is applied to the oil transfer station. Through the complementation of solar energy, cross-seasonal heat storage, natural gas and other energy sources, the cascade utilization technology of energy is used to provide a stable power supply and low-temperature heat to the transfer station. The annual energy saving rate of the proposed system is 42.2 percent, and the carbon reduction rate is 45.6 percent. The replacement of the energy supply system can effectively improve the energy utilization rate of the oil transfer station, thereby reducing carbon emissions and contributing to the energy conservation and carbon reduction of oil fields.
