陈永昌等.可自动校正的电缆注磁仪简介.测井技术,1994,18(4):276~280目前使用的电缆作记号装置存在一些缺点,由于电缆速度不同,使感应的接收信号产生的第二次注磁指令出现时差。造成磁性记号不准。本文介绍的电缆注磁器,将标准的接箍位置和长度系数储存在存储器中,把接箍测量、长度系数校正及自动注磁有机地统一在一个电子闭合环路系统中,实现了动态自动跟踪校正注磁。
The current cable magnetizer is not perfect. DUe to different cable movementvelocities, the second magnetizing command generated by the induced receiver signals often delays, which results in incorrect magnetic marks. The new magnetizerpresented in this paper, stores the typical collar locations and length parameters into a memory, and integrates the measurement of collar locations, length parametercorrection and auto-magnetizing into one loop so that dynamic' auto-tracing correction and magnetizing can be performed.
