主 题：Sijiazhuang Minefield Geothermal field Geothermal Negative anomaly Geothermal field differentiation Main control factors
摘 要：The research on geothermal field is one of the hot research content in the development of oil or gas and mining *** on the stratum temperature measurement data of 332 borehole in Sijiazhuang coalfield,the formation lithology and composed characteristics,geological and hydrogeological conditions,we did a research on the geothermal negative anomaly and its main controlling *** the research,we come to a conclusion:The modern geothermal field of Sijiazhuang coalfield is mainly effected by 3 factors:formation thermal conductivity,underground water and open *** high content of sandstone in coalfield layer causes strong thermal conductivity,fast heat conduction,difficulty in heat aggregation,which is the main controlling factors of low value in geothermy of Sijiazhuang coalfield;the strong regional groundwater runoff state is the macro control factors of its lower in modern geothermal field of this *** mine groundwater flow state play acoolingrool and the induced structural channel loss function to the surrounding rock temperature,which is an important control factor of geothermal negative anomaly and geothermal field varies in the study area;the open extensional fault and collapse column not only provide a good channel for geothermal loss,but also provide favorable conditions for the refrigeration to the surrounding rock from aquifer groundwater circulation and runoff,which is the key control factor to the geothermal negative anomaly and geothermal field varies of this coal field.
