介绍了大地电磁测深的最优分割法电性分层解释技术的基本原理,以及在冷水地区的应用效果.针对复杂构造,造成电阻率剖面失真的研究难点,引入地球物理测井资料解释中最优分割技术,提出了大地电磁测深资料的最优分割法。并通过模型实验和生产实验证实了该方法的可行性和有效性。采用该方法,在查明地质结构特征,发现新的有利勘探目标方面显示了良好的作用。
This paper introduces the basic principles of the electrical layered interpretation technique of the optimal segmentation method for earth magnetotelluric sounding and its application effect in cold water areas.Aiming at the difficulty in the study of complex structures and the resistivity profile distortions, the introduction of geophysical well logging data interpretation Optimal segmentation technology, proposed the best method of earth electromagnetic sounding data segmentation. Through the model experiment and production experiment, the feasibility and effectiveness of this method are verified. With this method, it has been shown to have a good effect in identifying features of the geological structure and finding new favorable exploration targets.
