摘要
根据国产井中磁力仪能计算钻孔中无磁干扰井段磁方位角,而引入受水平磁异常干扰产生磁方位异常Δβ的概念;并阐明Δβ的符号与水平磁异常ΔH方向的对应特性,从而得出Δβ曲线图型与磁性体相对于钻孔位置的关系,提出Δβ为井中磁测定位解释的一个辅助参量。
With the domestic borehole magnetometer,the authors calculated magnetic azimuth in the non-magnetic interference hole and introduced the concept of Δβ,which is called magnetic azimuth anomaly.The relationship between the symbol of Δβ and the direction of ΔH was clarified,and the relationship between the figure of Δβ and the magnetic body position was obtained.It is thus held that we can use Δβ as an auxiliary parameter in the calculation of magnetic source position.
