掌握磁场在整个空间上的分布特点，对地面磁测、井中磁测解正反演问题都是很重要的。如果我们把空间等值线看作一种曲线坐标，用它来解反问题，不仅方法简便、直观，同时一次可求得多个参数。此外，解释方法不受地形不平或钻孔弯曲的影响，也不要求实测曲线必须完整。并且可以判断所选用的曲线坐标是否合适，以保证得到正确的结果。 Grasping the distribution characteristics of the magnetic field in the whole space is very important to the ground magnetic surveying and the positive inversion problem of the well magnetic survey. If we consider the spatial contour as a curvilinear coordinate, we can use it to solve the inverse problem, which is not only simple and intuitive, but also obtains multiple parameters at one time. In addition, the interpretation of the method is not affected by uneven terrain or drilling bending, nor does it require that the measured curve must be complete. And you can determine the choice of the coordinates of the curve is appropriate to ensure that the correct result.
