摘要:
针对雷击电磁辐射对录井系统的危害问题，建立了录井系统线路雷击危害模拟试验模型，采用8/20 μs冲击电流发生器，开展了录井系统的雷击耦合试验，定量分析了雷击电磁辐射对录井系统的影响。研究结果表明：随着电流的增大和距离电流通道的减小，耦合的电压随之增大；线缆长度越长耦合的电压越大，最大耦合电压达到了2 720 V；屏蔽层接地可以有效地减小电磁辐射对线缆的耦合作用。
Abstract:
Aiming at the hazard of electromagnetic radiation caused by the lightning stroke on the logging system, a simulation experimental model on the lightning stroke hazard to the circuits of the logging system was established. The lightning stroke coupling experiments of the logging system were carried out by using the 8/20 μs impulse current generator, and the influence of electromagnetic radiation caused by the lightning stroke on the logging system was analyzed quantitatively. The results showed that the coupling voltage increased with the increase of current and the decrease of distance to the current channel. The longer the length of cable, the larger the coupling voltage, and the maximum coupling voltage could reach 2 720 V. The grounding of shielding layer could effectively reduce the coupling effect of electromagnetic radiation on the cable.
