It illustrates characteristics of stratum in Yuncheng basin, analyzes overall condition of geothermal water resources and its characteristics, which to offer scientific reference for exploitation and utilization of geothermal water resources in this district,and to promote quick development of our economy.
The author has preliminarily estimated the development prospects of the geothermal water resources in Zhengzhou City,and put forward the feasible proposal to protect it. Finally,the author appeals to the whole society to pay attention to the protection of the geothermal water resources.
The article analyzes the main environmental issues caused by exploitation of terrestrial heat resources: earthquake, land subsidence, exhaustion of terrestrial heat resources, pollution by harmful composition of terrestrial heat water, heat pollution etc. , and proposed control recommendations.
According to calculation of geotermal resources in reservoirs,total geothermal resources in reservoirs is 11.78×10~(10)m~3.Except residual volume of water in reservoirs,geothermal resources in reservoirs is still 8.7×10~(10)m~3.Thereby Dumen area is a commercial value place of geothermal resources.
In this paper, the characteristics of water source heat pumps combined with deep and shallow wells, in which well side heat pumps were connected in series, were investigated through both design example and on-the-spot experiments,for the purpose of father utilization and energy saving of groundwater source.
According to synthetic interpretation and processing of varied geological,hydrogeological,inte-grated geophysical and drilling data,analysis of geothermal fields of different depths and studies of characteristics of geothermal pools,geothermal hot water energy resources in northern Songliao Basin are comprehensively evaluated in this paper.
A radial inflow turbine has been developed for binary-fluid-cycle geothermal power production. In this paper are presented its technical and economic evaluation. Efficiency of the turbine and its basic design parameters are theorotieally analysed. Construction and speciality of manufacture and test approach of the testing unit are also described. Results of tests show that the radial inflow turbine has many advantages such as simplicity in construction and manufacture, high efficiency and low cost. It is sp...
The article points out that the Ordovician System-Limestone formation of Xianyu syncline situated in the Western Hills of Beijing is an independent reservoir and transporting structure of ground-water embedded about one thousand meter below.The west end of this structure goes upward and intersected by the Yongdin River, so it may get the alimentation from the river to the volume about 10m3/sec.At the both wings of its northeast end the karst water runs out of the ground as springs, such as Yuquanshan founta...
On the basis of the equilibrium temperature data measured in 26 holes, 1690 temperature measurements of oil-bearing layers, artesian flow rate and temperature logging data of 21 thermal water wells and the result of mathematical simulation of regional geothermal field, a review of the characteristics of geothermal pattern and the prospects of utilization of thermal water for the region studied are given in this paper.Main conclusions are as follows:(1) The northern plain of Shandong province geologically is...
