GEOTHERMAL GEOLOGICAL CHARACTERISTICS AND EXPLOITATION POTENTIAL IN NANYANG BASIN

ABSTRACT
Based on the geothermal geological conditions and the geothermal resources development and utilization data of Nanyang Basin for many years, the geothermal fields in the basin are divided according to the study of fault structures. According to the pumping test data of geothermal wells, the permeability coefficients of the thermal storage aquifers of the geothermal wells were calculated using the steady-flow Dupuit formula and Kusakin's empirical formula. In this paper, the water conductivity of thermal reservoir is calculated by using the method of line diagram and recovery water level, and the characteristics of thermal reservoir aquifer group, geothermal fluid-flow field, and hydrochemistry are described systematically. Based on the analysis method of groundwater exploitation potential index, the development and utilization potential of geothermal resources is studied, which has certain reference significance for the development and utilization of geothermal resources of sedimentary basins.
