岩心钻探作业雷电防范措施浅析

Discussion on Lightning Strike Protection Measures of Coring Drilling

摘要:

岩心钻探作业作为地质勘查一种重要手段，其作业场所大多位于郊区或野外，作业所使用的钻机、钻塔及其附属件几乎全部为金属构件，其设备在地面上相对位置凸出，极易遭受雷电袭击，在当前钻探作业中，雷电防范未能引起施工队伍的足够重视，在防雷设施使用和安装上存在不少问题。通过运用雷电防范原理分析钻探设备防雷系统，对岩心钻探作业的防雷措施作讨论，以便为钻探施工队伍正确使用各种防雷方法作参考。

Abstract:

Coring drilling is an important method of geological exploration and most of the workplaces locate in suburb district or open country; while drilling rig, drilling tower and the subsidiary pieces are almost made of metal, and the drilling equipments are protruding on the ground, which are subjected to lightning attacks. In the drilling operation, most exploration teams do not pay enough attention to lightning strike protection; there are some problems in application and installation of lightning strike protection facilities. In this paper, discussion was made on lightning strake protection for drilling operation based on the analysis on lightning strike protection system of drilling equipment by the principle of lightning strike protection.
