摘　　要：通过对方向(Tilt-Euler)公式的推导,同时现场试验建立磁化方向不同、形状不同的4种理论简单模型,在此基础上进行磁探物体的三维坐标反演,同时通过实际的海洋磁探项目进行方法的论证,探讨方向Tilt-Euler法在海洋磁探中的反演优势。结果表明方向Tilt-Euler法仅通过磁测数据就可以快速推断出异常体的中心点坐标和大概深度,相比于Tilt-Euler法,方向Tilt-Euler法反演解更加收敛、连续性更好、磁源预测准确度更高、受环境影响小,实用性更强,计算更简便。这对于大面积的海洋磁探资料处理具有重要意义。Through the derivation of the direction(Tilt-Euler)ormula and the establishment of four theoretical simple modelswith different magnetization directions and shapes through on-site experiments,three-dimensional coordinate inversion ofmagnetic exploration objects is carried out on this basis.At the same time,the method is demonstrated through actual marinemagnetic exploration projects to explore the inversion advantages of the direction Tilt-Euler method in marine magneticexploration.The results show that the direction Tilt-Euler method can quickly infer the center point coordinates andapproximate depth of the abnormal body only through magnetic measurement data.Compared with the Tilt-Euler method,theinversion solution of the direction Tilt-Euler method is more convergent,has better continuity,higher accuracy of magneticsource prediction,is less affected by the environment,has stronger practicability and is more convenient to calculate.This is ofgreat significance for the processing of large-scale marine magnetic exploration data.
