Dianci bileiqi, 2020 针对西北地区输电线路和埋地油气管道相邻交叉,输电杆塔接地体可能在雷电冲击下对油气管道放电的情况,通过试验的方法确定了针电极对油气管道间砂质土壤的平均击穿场强,分析了临界击穿场强的影响因素,并对土壤的击穿机理进行了讨论。试验结果表明沙质土壤中针电极对管道的临界击穿场强为200～300 kV/m,土壤电阻率对土壤的临界击穿场强影响不大,为确定西北砂质土壤地区输电线路和埋地油气管道的安全距离提供了参考数据。

Design and Implementation of Oil and Gas Pipeline Energy Consumption Forecast System Based on SCADA System [PDF]
, 2015 随着我国油气管道事业的快速发展，原油、成品油、天然气管道局部已形成管网并形成集中调控，我国陆上长输油气管道总里程将近13万公里，笔者所在的工作单位北京油气调控中心承担着中国80％的油气管道的调控运行，但管道运行能耗处于较高水平，管道运行管理水平处于较低水平，国内油气管网优化运行技术较国外还存在较大差距,加之近期国际油价持续大跌，中石油等能源企业迫切需要降本增效和开源节流，通过技术手段节能降耗成为关注焦点。再者传统的个人经验式管理已无法满足日益增长的管理难度需要，为解决这一矛盾 ...

Dianci bileiqi, 2020 为了研究输电线路故障状况下,接地网散流对临近油气管道安全运行造成的电磁干扰。基于实际工程参数,建立了输电线路在雷击情况下,对油气管道电磁干扰模型。采用CDEGS防雷计算软件分析了雷电流幅值、土壤电阻率、线路与管道间距对管道感应电压的影响规律。对比了输电线路两种状态运行下采用排流线（裸铜带）保护前后管道感应电压防护效果。计算结果表明:增加管线间距与敷设屏蔽线后管道感应电压明显降低。研究结论可为油气管道设计施工及安全防护提供参考。

The Research on Steel Plate Defects Inspection by Magneto-acoustic Testing with Induction [PDF]
, 2015 随着工业化的发展，钢材被应用在了各种各样的领域，比如：天然气管道、轮船、汽车等等。然而，随着时间的推移，钢材在使用过程中会出现腐蚀、裂纹等缺陷，这些缺陷严重影响了使用的安全，所以必须在事故发生之前对其进行检测以评估其安全性。本文在对比多种无损检测方法及研究感应式磁声成像的基础上提出了感应式磁声检测的新方法。该方法是在静态磁场下，通过脉冲电流激励被测钢板表面，进而在钢板内部发生电－磁－声的相互转化，最后提取钢板表面的磁声信号。该方法与被测材料无接触，无耦合，可在恶劣环境下进行工作，非常适合钢板的在线检测。
