Development and Application of Volatile Organic Compounds Diffusion Simulation System in an Oilfield
In view of the absence of small-scale atmospheric diffusion models and the characteristics of volatile organic compounds(VOCs)pollution in oil and gas fields,this paper developed a multi-species and multi-emission small-scale reactive atmospheric diffusion model system based on spatial analysis method and Gaussian plume model,which includes four models:point source without chemical reaction,point source with chemical reaction,non-point source without chemical reaction and non-point source with chemical reaction.The SharpDev project development framework is used to build the system,and Python language is used to develop the background calculation process,so that it can automatically calculate the pollution diffusion situation of oil and gas field station source and non-point source according to the user input parameters,and complete the visual display.The development and application of this software system provides a method basis for the diffusion,migration and prediction of air pollutants in similar oil and gas fields.
