Yatsyshyn T. Perfecting reduction methods of anthropogenic pollution of atmosphere at oil wells drilling.

The object of research – the emission processes of dangerous substances to the environment as the result of drilling fluid evaporation during well-drilling. The subject or research – the equipment of pump-circulating drilling system, methods of estimation and forecasting the environmental danger rate of the DR in terms of polluting PCS evaporations. The methods of research – in order to investigate the process of diffusion of dangerous substances as a result of drilling fluid evaporation physical and mathematical modeling, laboratory and industrial experimental investigations applying up-to date control instrumentation have been used. In order to calculate the dispersion rate of harmful components in the air the newly created MAPEDF program was used. Statistical treatment of the results was performed by regressive analysis method with the application of program packages. The implementation rate – “The methods of environmental safety estimate of atmosphere pollution by drilling fluid evaporations” at Stryi (boring department) BD DR “Ukrbudgaz”. The branch of implementation – mining operations enterprises.
