油田钻井井场危险区域的划分

摘要

分析了油田井场危险区域的特点,介绍了国内外关于爆炸性危险场所划分涉及到的相关标准、法规及对危险场所划分的相同性和差异性.根据目前实际情况列举了石油钻井行业应用最广泛的美国APIR500标准对井场防爆危险区域具体划分的图例,以便于相关人员设计井场标准化防爆电路和选择不同类型的防爆电气设备时参考.%The characteristics of hazardous zones for oilfield drilling site,relative standards of explosive gas atmospheres both at home and abroad were his article analyzed, the same and difference of all kinds of standards and codes as well. According to the reality conditions of current oilfield drilling,some division figures of hazardous area in oilfield drilling site of APIR500 standards were cited. It was convenient for selecting and designing standardized explosion-proof electric control system and all kinds of explosion-proof electric apparatus.
