Аnnotation
Classes and sizes of explosive zones of reservoirs are set with light oil products depending on the terms of their storage: into a reservoir, round respiratory to the valve that does not eliminate the coil of dangerous vapour from a reservoir in an atmosphere, and during rapid uncatastrophic depressurization of reservoir. Calculations came true by three methods: by the calculation method of determination of hypothetical volume, calculation method with the use of nomograms and determined method. The calculations executed by the determined method do not answer the results got with the use of calculation methods. Calculations, determinations of hypothetical volume conducted by a method, the high sizes of explosive zones give pain in comparing to got a method with the use of nomograms. Classes and sizes of zones after the determined method are fixed and case insensitive environment. Into a reservoir the explosive zone of class takes place 0. Round a respiratory to the valve reservoir depending on the rate of movement evaporation through opening to the valve at different speeds of wind at normal terms after calculation methods time of existence of explosive zone is maximal in default of the forced dispersion of explosive mixture. At the increase of rate of movement evaporation through opening of respiratory to the valve increase of radius of explosive zone it takes place on a logarithmic law. The change of temperature results in the insignificant change of radius. During depressurization of reservoir of increase of radius of explosive zone at the increase of speed of source takes place also on a logarithmic law. Radius of zone, got the method of determination of hypothetical volume have in two times exceeds the radius expected by a method with the use of nomograms. A maximally possible radius presents a 20 m and 9 m accordingly at speed of source of petrol 10 kg/s a radius is fixed the Determined method at the level of a 3 m for all terms of source.
