等深模式电极序列法电测深研究
|
摘要
从均匀半空间体元电阻率变化出发,介绍了响应函数的基本原理,并以对称四极测深为例,说明了等深模式电极序列法的基本思想。通过实例,探讨了等深模式序列方法相对传统方法在优化电极序列、增加目标深度信息密度、提高深度分辨能力等方面所具有的优势,结合反演结果,分析了利用等深模式序列快速估算异常体深度的合理性。
Based on a study of the change in the resistivity for voxel in homogeneous half-space,this paper describes the basic principles of the response function. Focusing on the symmetric four-pole sounding,this paper also deals with the basic idea of equivalentdepth-mode electrode sequence method. With a practical example,the advantages of this method are discussed in the aspects of optimizing the sequence of electrodes,increasing the density of target depth information,and improving the capability of depth resolution.Based on the inversion results,this paper analyzes the feasibility of the estimation of the depth of the anomalous body by using the equivalent-depth-mode electrode sequence method.
