摘要
电缆磁性记号作为测井射孔的深度标准，在油田勘探开发中占有极其重要的地位。人工丈量做记号，深度误差大，工作时间长。文章介绍了两种电缆自动注磁方法的深度控制原理、并对系统各部分进行介绍，该系统一次下井可完成电缆自动注磁、磁定位测量任务，深度误差符合ＳＹ／５１３２《测井原始资料质量要求》的规定标准的要求。
Logging cable magnetic mark, as the standard of perforating depth,lays an important role in the exploration and development of oilfield. The error of depth is significant and the job time is fairly long for man-made marking on logging cable. Two kinds of principle for logging cable automatic magnetic mark system as well as every part of the system are introduced. This system can do the task of CCL measuring and automatic mark making on logging cable in one trip. The depth error meet the requirtmet of SY/5132, the quality requirment of original logging curves.
