摘　　要：介绍了国外的各类电磁场/磁场矢量引导系统的结构和应用范围,对磁场矢量引导系统核心部件进行了研究,建立了适合于与钻头相连接的管柱形磁体的三维空间磁场模型。应用磁体空间磁场规律的基本公式,推导了管柱形永磁体的三维空间磁场规律计算公式。根据磁探测系统测量到的磁场分量,利用规律计算公式和相应辅助计算软件,得到管柱形磁体源与磁探测系统之间矢量距离的计算规则,并对矢量距离计算规则进行了验证和分析。The structure and application of various kinds of electromagnetic-magnetic vector guide systems were introduced. The key parts of the magnetic vector guide system were discussed. A three-dimensional magnetic field model suitable for the tubular magnet connected with drilling bit was established. The fundamental formulae of magnetic field were used to deduce the formulae for the three-dimensional magnetic field of tubular magnet. According to the magnetic field ingredients, formulae and the corresponding soft-ware,the calculation law of vector distance between tubular magnet source and measurement system was obtained and was applied to analyze the magnetic field of tubular magnet.
