华北地区基岩热储回灌段地温场变化特征及热源分析
Variation Characteristics of Geothermal Field and Heat Source Analysis of Bedrock Thermal Reservoir Recharge Layer in North China
摘要
Abstract
Based on the study of Xianxian geothermal field,a typical bedrock geothermal field in the North China Plain,the vertical temperature field of the bedrock thermal reservoir reinjection well is monitored,and the variation characteristics of the geothermal field of the reinjection well after the heating season are discussed,and the heat source of the temperature recovery in the reinjection section of the bedrock thermal reservoir is comprehensively analyzed.The research result indicates that continuous low-temperature reinjection during the heating season can cause a significant decrease in the thermal storage temperature in the reinjection section of the reinjection well,and the recovery rate of the thermal storage temperature is slow during non heating seasons.The main heat source for the recovery of bedrock thermal storage temperature in the Xianxian area after the heating season is the conduction of relatively high temperature strata around the thermal storage layer and the heat brought by the flow of relatively high temperature geothermal fluids in the same layer.The concentrated development zone of bedrock thermal storage in North China should be more reasonably arranged with extraction and recharge wells to increase the effective service life of the thermal storage.关键词
