[Abstract]:Under the background of promoting renewable energy instead of traditional energy structure in the international environment, geothermal resources, as an important component of solar energy resources, can make great contributions to China's economic take-off. In recent years, some scientific researchers have studied the development of shallow geothermal energy, accelerated the development and utilization of geothermal resources, and became underground. The new direction of water science and engineering development. Through the investigation of the shallow geothermal energy resources in Changchun City, this paper reveals the geothermal storage conditions and the distribution of shallow geothermal field in the study area, and makes a suitable zoning for the exploitation and utilization of shallow geothermal energy resources. On this basis, the geothermal energy resources in the study area are applied to the geothermal energy resources in the study area. The total amount of shallow geothermal energy resources in Changchun urban area is calculated, which provides important data support and scientific feasible scheme for the development and utilization of shallow geothermal energy in Changchun city. The following points are obtained: (1) the paper analyses the geotechnical characteristics of shallow geothermal energy stored in Changchun urban area. The water rich, water temperature and water quality of the bedrock fractured water in the platform area restrict the utilization of shallow geothermal energy. Among them, the amount of the residual resources of groundwater in the Yitong valley area is more, and the recharge conditions are good. The water source heat pump can be developed and utilized on the basis of the water quality requirements. The groundwater of the Jia Jia depression and the four bedrock rich water zones in the platform area The water quality is better, but the amount of residual water resources is less; the amount of surplus water is more abundant in the rich water area of the Xing Long Gully. It is necessary to appropriately increase the ratio of groundwater resources exploitation in this area, apply the groundwater more in heating and maximize the utilization of energy. (2) the actual thermal physical parameters of different lithologic geomorphic units are tested and background data have been obtained. The thermo physical parameters of three different types of stratigraphic structures in the area are summed up. On this basis, the temperature field of the study area is studied. The temperature changes of different boreholes and different depths are analyzed. The results show that the average geothermal gradient in Changchun urban area is 2.88 /100m. The temperature of the urban area is relatively high. This conclusion provides a clear and reliable direction for the selection of the shallow geothermal energy utilization in Changchun urban area. (3) the paper uses analytic hierarchy process to evaluate the suitable area of water source heat pump and ground source heat pump in Changchun City, which will be distinguished as the suitable area of water source heat pump. The suitable area, the general suitable area and the unsuitable area are: area I (Jia Jia Wa Zi - eight liipu - Xing Long Gou base rock fissure water zone in the west area) is an unsuitable area for underground water source heat pump, and the eight Libao water rich zone in the second area is the suitable area for underground water source heat pump, and the water source is established in the most areas of the Jia Jia Wa Zi Xing Long Gou section and the third area Yitong Valley region in the second region. The suitable area and general suitable area for the heat pump development system. (4) the water heat coupling simulation model of shallow layer geothermal energy is established in the suitable area of the water source heat pump. The model is solved by TOUGH2 software. The model is identified and verified by the observation data of water temperature and pressure in the study area. In the year of 2011, the model is used for research and research. The temperature field and pressure field in the next 10 years are predicted, and the temperature field and pressure field change of the pumping well and the recharge well in the groundwater source heat pump system in the study area are discussed. The conclusions are as follows: (1) the pumping well is directed back in the direction of hydraulic gradient under single pumping and single injection mold. Under the condition of well irrigation, the design pumping amount is 2 area, the third area is 500 m3/d, 800 m3/d, 1500 m3/d. Under the spacing of 30m, 50m, 80m, 100 m and 150 m, the relationship between the heat breakthrough time and the rational well spacing is simulated. The results show that the time of heat breakthrough in the third zone is longer than that in the second zone; after the system operation, after 10 years, II zone The temperature field decreased by 0.7 degrees C, and the temperature field in the third area decreased by 0.6 degrees C. To 2022, the thermal storage pressure was reduced to 6.1 x 104Pa. (2) under single pumping and double irrigation mode, and 5 kinds of well distribution schemes were simulated respectively. Under the influence of heat breakthrough and temperature field, the following conclusion can be drawn: the linear well layout scheme a (two recharge wells are located on the same side of the pumping well, and pumping. " In the upper reaches of the water well and the folded line type well scheme D (two recharge wells and pumping wells vertically arranged, and the drainage well located at the upper reaches) is the best well distribution scheme. When the pumping amount is 500 m3/d, 800 m3/d and 1500 m3/d, the reasonable spacing of the well distribution is 75m, 90m and 150m, 70 m, 90m and 150m., the water source heat pump system operates for 10 years. The influence range of the degree field is 400m x 200m, the temperature field is reduced by 0.5 degrees Celsius. By 2022, the thermal storage pressure drop is 5.1 x 104Pa, the annual water level amplitude 0.52m. (5) is used to calculate the shallow geothermal capacity of the study area by the thermal equilibrium theory. The results show that the thermal capacity of the second region is 3.9 x 1013kJ, the thermal capacity of the third region is 8.1 x 1013kJ, the total heat capacity is 1.2 x 1014kJ.. From the calculation results, the groundwater is an important thermal storage medium and the thermal capacity is relatively high in the groundwater storage area in the second and third areas. In the underground water source heat pump and the calculation of the heat exchange power of the soil source heat pump system, the best well spacing is introduced into the subsurface water conversion method to calculate the regional heat transfer power. The conclusion is that the Changchun Yitong Valley pine is pine. The total heat transfer power of the ground water source heat pump system of the sandy gravel and the weathered zone of the Qingshankou bedrock is 33.4 x 104 kW (winter) and 66.8 * 104 kW (summer), which can be used for heating 668 x 104m2 buildings and refrigerating for 835 104m2 buildings.
