Therefore, efforts to reduce evaporation loss, is the construction of an energy reserve is important work. In recent years, with domestic energy-saving, environmental protection and safety issues growing emphasis on oil and gas depot loss research has made a lot of achievements. This paper analyzes the reasons for loss caused by oil and gas depot and influencing fac
