In recent years,with the rapid development of China's economy,oil plays an increasingly important role in people's lives.As an important storage device for petroleum products,the importance and status of oil storage tanks cannot be ignored.The use also makes its security issues require in-depth research.The fire dam is an important barrier to ensure the safety of the tank area.Whether the design of the fire dam is reasonable and whether the tank can effectively block the spread of oil when the tank is accidentally sprayed will play a very important role in the safety of the tank area.In this paper,ANSYS finite element analysis software is used to simulate the phenomenon of oil injection in the event of a reservoir accident,and the leakage of the storage tank is analyzed from the injection pores of the storage tank and the injection of oil from the storage tank to the ground.The mechanism of jetting oil and the characteristics of the flow field.In this paper,the numerical simulation method is applied to obtain the flow field characteristics in the pores of the tank pore injection oil and the flow field of the tank injection oil to the ground.The results show that the oil is uniformly accelerated in the injection pores,and the magnitude of the acceleration is related to the pore size.The acceleration of the oil in the pore increases with the increase of the pore size;the magnitude of the acceleration in the pore and the initial velocity of the jet also exist.Relationship,the acceleration of the oil in the pore increases as the initial velocity of the injection increases.In the study of tank injection oil to the ground,when the injection height is 3,5,7m,the tank injection oil will directly impact the fire dam.When the injection height is 9m,the horizontal distance of the oil injection is at the fire dam.Within the protection range;as the injection height increases,the flow rate of the oil injection decreases,and the horizontal distance of the oil injection gradually becomes smaller;when the injection height is the same,the injection aperture is 0.3,0.4,0.5 m,As the injection aperture increases,the flow of the injected oil increases,the flow rate of the oil in the center of the stream is the largest,and the velocity of the oil gradually decreases from the center of the stream to the sides;as the injection aperture increases,the storage The fluctuations in the oil inside the tank are becoming more apparent.The horizontal distance of the tank injection oil does not change as the injection aperture changes.
