Study On The Geothermal Resources Latent Capacity Of Tiefeng District QiQihr

Base on deeply research on the regional tectonic, fault activity characteristics andmagmatic activity features through geologic history in the area called Tiefeng area, located inQiqihar, the thesis analyzes geothermal field characteristics and factors that affect itsdistributions in the study area. The regional sedimentary setting, the stratigraphic sequenceand single well phase analysis of three key wells of the study area are included in this paper,getting the plane distribution laws of sand body. According to the research on petrologycharacteristics of the geothermal reservoir and sandstone diagenesis, the paper makespredictions on the distribution rules of property features of the geothermal reservoir inhorizontal and vertical plane. Through the analysis of regional hydrogeology conditions, thepaper carves out of the plane hydrogeology units as well as the profile hydrogeology zones.The combinations of the geothermal reservoir are classified while illustrating the rechargearea, the drainage area, the migration pathway of water, its forces and directions. The articleanalyzes the water chemical field of the study area to make water quality assessment,demonstrating the chemical composition of water and its vertical zonation, the water salinityand water-type distributions and all that for the identification of geothermal reservoir waterquality. Single well natural production capacity forecast model of geothermal reservoir andvolume of geothermal water resources forecast model are established which results in thecalculation and comprehensive evaluation of geothermal resources. All have done put forwardreasonable proposals to provide a theoretical basis for the further exploration anddevelopment work.
