Investigation on Environmental Risk Visualization of Oil Field Accident Based on GIS

Based on the detailed identification of the sources of oil field accidental risk, this paper integrated geographic information systems (GIS) and dispersion model of environmental pollution and set up a visual early warning platform for oil field accident risk disasters, using the combination techniques of GIS and environmental models of VisualBasic and Mapobjects. The results showed that the system achieved concentration calculating of forecast points, and initially achieved the visualized expressions of the atmospheric environmental risk prediction on the GIS platform. It provided technical support of atmospheric environmental risk assessment, and has great significance and application value to oilfield production safety, accident and rescue and environmental protection.
