GDP32ⅡCSAMT TEM中的应用与研究.docx

桂林工学院硕士学位论文ABSTRACT 桂林工学院硕士学位论文 ABSTRACT The Controlled Source Audio-frequency Magnetotellurics(CSAMT)and the Transient Electromagnetic Methods(TEM)are both belonged to the Artificial Active Source Electromagnetic Methods．Having the bigger exploratory depth，and thanking for the stronger resolving power for electricity and the convenienter way of measures，in recent years，the Electromagnetic Methods has been widely made use of in the metal mineral，petroleum，engineering exploration and many realms of etc，and acquired lots of achievements remarkablely in these fields．With the progress of theories of computer technologies and electronic measures about electromagnetism，instruments of electromagnetic exploratory have nowadays taken greater development．The GDP-32“，as a kind of multi—functional electric instrument，，has undoubtedly the most advanced level in the world Oil the collecting and interpreting datum in the CSAMT and TEM，However, being used of the artificial source，showing all kinds of coupling effects its own self and misunderstanding the GDP-32“，some native geophysical companies are annoyed with all kinds of trubles(the effect of near soure，the electromagnetic interaction)tO process and interpret datum on practices． The paper has studied the data file of CSAMT／TEM for GDP．32u,and refined informations from these data files，determined the method about CSAMT with sources of different directions，put forward increase or decrease the number of“triangle’’coefficients dynamicly for being closed to source，made out the thinking of selective frequency space through comparing with kinds of effects to adjust static,evaluated the data with points of view effectively，and made out interrelated programs with FORTRAN language finally． In practical processing and operation，the paper has determined the work method about CSAMT through different directional sources，distinguished static effects from line 1 13 and line 1 14 of the project in Guangxi Fuzicong effectively，and adjusted them
