The Application Of Geophysical Techniques In The Geothermal Exploration Of The Suzhou District

Geophysical exploration is one of the most important means of investigation of deep geothermal resources. According to the site topography and geological conditions,the working face detection depth requirement for high precision, strong noise interference, the challenge of a single geophysical method is hard to pinpoint predict the output of the ore bodies and the occurrence state, need comprehensive geophysical prospecting method,mutual constraint,mutual complement,good ore-prospecting effect can be achieved.Based on the high precision magnetic profile of the regional aeromagnetic anomalies, and the high precision gravity profile measurement, the division of the regional basis is determined. Later section for transient electromagnetic sounding of controlled source audio-frequency magnetotelluric sounding profiles and divides the formation lithology electrical determine edge in Cenozoic basin basement buried depth, fault location, occurrence and distribution range and depth of the thermal storage The optimal development location of geothermal resources is inferred, and the geophysical basis is provided for the establishment of geothermal drilling holes.Through the field investigation of the exploration area, combining the regional geological data, the research results, and the comprehensive analysis of geophysical data, Deduce the F1, F2 and F8 three has better into hot prospects of main fault belt,and determine the three fault geothermal hot conditions are ripe, advances some Suggestions on the geothermal drilling test hole location layout, achieved the purpose of the exploration.
