ANALYTICAL CONTINUATION OF MAGNETOTELLURIC FIELD——METHODS AND APPLICATIONS

Hu Wenbao ( Computing Centre, Jianghan Petroleum Institute ) Chen Suyang Deng Xiaolin ( J iangsu Petroleum Exploration Bureau )  
The magnetotelluric field observed on the earth surface is the combination of the normal and abnormal fields. The abnormal part of the observed field is the total contribution of the shallow, deep, vertical and lateral conductivity inhomo-geneity in the earth crust. The interpretation results by conventional methods are not quite reliable due to the seriously distortion of the lateral inhomogeneity . In order to study the magnetotelluric data interpretation methods for complex geoelec-trical structure, methods of .analytical continuation for electromagnetic field of the earth and their possible application are discussed in this paper . The upward continuation of magnetotelluric fields can be conducted by means of the analytical solution or spectral solution of electromagnetic field in free space. For downward continuation, both lateral homogeneous and inhomogeneous cases are considered. In laterally homogeneous medium, downward continuation can be conducted in wave-number domain by means of the Stratton-Chu integral and the spectral ex-pansion of Green function. In laterally inhombgeneous medium,the classical method of Taylor series expansion is used for downward continuation.For application,the different methods can be chosen for different conditions.
