CSAMT Looking For Geothermal Resources Application In Nina Of Heilongjiang Province

CSMAT method is a kind of exploration method, rapid development in recentyears, use of controllable source audio frequency CSAMT method can effectivelyjudge, groundwater occurrence. The geothermal resource survey and reasonableapplication of geophysical methods, especially controllable source audio frequencyCSAMT method not only can guide drilling position, also can reduce the workload,shorten the period and reduce the cost.In this paper, the main research work aims at the analysis of researchachievements on the basis of development, geothermal resource survey. Using thegeochemical and geophysical methods in search of work area of distribution of basaltand Quaternary Cover under thermal storage tape (layer) of development area,screening out the next step in geothermal exploration target area, preferably ageothermal drilling well, for the next step of construction of exploration with miningwells is provided utilizing. The work on the work area underground heat storageconditions of underground water occurrence regularity and the development prospectsof preliminary evaluation.1. the main contents of this paper are as follows:①the full collection of work area within the regional geology, structural geology,hydrology geology, geophysical (electric, magnetic and gravity), geochemical data.Comprehensive analysis and study, the reasonable arrangement of the geothermalresource survey.②In the working area using comprehensive geophysical and geochemicalmethod, analytic underground deep tectonic fracture distribution and waterdistribution building structural geology model.③through comprehensive analysis of various data, determine the position of geothermal drilling well.2.this study examines physical workload as follows:①controllable source audio frequency CSAMT sounding to work, the measuredpoints to1144, in which the net degree is1000×200m measuring point789, netdegree is100×50m measuring point355. The area is150km2.②In CSAMT sounding measurements, a profile, a total of11points, point to4km, section40km.
