Study on VOCs Diffusion Simulation in Typical Stations of Longdong Oilfield
The oil and gas diffusion mechanism was emphatically analyzed by field investigation,testing and numerical simulation,combined with Gaossian plume diffusion model for a united station in Longdong Oilfield.The results indicated that attention should be paid to the superposition of VOCs on the leeward side behind the storage tank,which could easily lead to oil and gas accumulation.Meanwhile,VOCs diffusion presented an overall downward trend due to the role of gravity and eddy currents.VOCs diffusion was hindered by upwind buildings and fire dikes,while the VOCs concentration reached the explosion limit range between tanks,three-phase separation areas,and fire dikes,which was easy to cause fire and explosion.Through VOCs diffusion simulation research,it was concluded that the site needed to strengthen airtight management,and there was safety risks of the VOCs escaping from crude oil storage tanks,so it was necessary to adopt an integrated oil and gas recovery system for collection and treatment.
