Oil field chemical safety gas sampling and detecting device

The invention relates to an oilfield chemical safety gas sampling and detecting device which effectively solves the problems that in the prior art, the concentration of oilfield petroleum gas cannot be comprehensively detected, a pipeline cannot be rapidly detected, and a high-concentration point of the petroleum gas cannot be positioned in time. According to the technical scheme, the device comprises a support and a sleeve; a box body; a detection chamber; a gas detector; an air collecting bin; a hood; a wind vane; four supports are arranged on the periphery of each oil pumping unit, two adjacent oil pumping units share one support, and the direction of the wind indicator is the air quality of the oil pumping unit detected by the corresponding box body and the gas detector. The device is simple in structure and convenient to operate, can effectively improve the detection accuracy of petroleum gas in the air of the whole oil field, also can realize quick positioning of a gas leakage point of a pipeline when n
