近年来,中国的海上油气田发展迅速,特别在钻井设备方面取得了很大的突破。由于钻井设备分布着大量电子电气设备及易燃易爆危险品,容易受到雷电危害。本文从直击雷与雷电感应两个角度入手,分析了钻井设备可能遭受的雷电危害形式,提出了相应保护措施和建议,对海上油气田钻井设备的雷电防护具有参考意义。 In recent years, China’s offshore oil and gas fields have been developing rapidly, and a great breakthrough has been made especially in drilling equipment. Due to the distribution of drilling equipment, a large number of electrical and electronic equipment and flammable and explosive dangerous goods, vulnerable to lightning hazards. This article starts from the two aspects of direct lightning and lightning induction, and analyzes the forms of lightning damage that drilling equipment may suffer. The corresponding protection measures and suggestions are put forward, which have reference significance for lightning protection of drilling equipment in offshore oil and gas fields.
