摘　　要：防雷接地装置是防雷系统运行的基础,而腐蚀是接地装置失效的主要原因,金属材料的腐蚀速率是接地装置选材和规格确定的重要指标。针对胜利油区土壤电阻率低、盐碱度高的特点,通过对金属接地材料进行埋地腐蚀试验,测试其腐蚀速率,确定适合胜利油区的防雷接地金属材料。根据测试结果胜利油区防雷接地金属材料应优先选取热镀锌钢,其次为碳钢、普通钢,特殊情况可考虑采用不锈钢、铜,同时给出了不同防雷接地金属材料接地体规格参数。Lightning-proof grounding device is the basis of＇the lightning protection system, and corrosion is the main reason For the Failure of grounding device. The corrosion rate of metal materials is an important index to determine the selection and specification ot-the grounding device. This paper aiming at the characteristics of low soil resistivity and high saline and alkaline for Shengli Oilfield, through the buried corrosion test of-metal materials, and the corrosion rate test, according the result to determine the right metal materials for lightning of-Shengli Oilfield. The first choice for the lightning of Shengli Oilfield is hot dip galvanized steel, the second is carbon steel or common steel, for the special circumstances can select stainless steel or copper. At last, the tests provide the specification parameters of grounding body of metal materials for lightning.
