摘要
针对河南省东部平原埋深1000~1300m、1300~1600m热储层的特征,利用Larson指数法评价了两热储层地热水的腐蚀性和结垢趋势。根据腐蚀性,确定1000~1300m、1300~1600m热储层地热供暖时应分别采用直接和间接供暖形式。利用时间资金价值法,评价了1000~1300m、1300~1600m热储层地热供暖时的无调峰和调峰供暖方案,并与通用的锅炉供暖方案进行了对比,优选出了调峰地热供暖方案。另外,在1000~1300m和1300~1600m热储层均存在的地区,对两热储层的独立供暖和联合供暖模式进行了经济分析,可以看出:联合供暖显著优于独立供暖模式。
Aim at the features of hot reservoir in depth of1000~1300m,1300~1600m of eastern plain in Henan Province,and used Larson exponential method,the corrosiveness and calculous trend of geothermal water in two hot reservoirs have been evalu-ated.Based on the corrosiveness,determined that geothermal heating with hot reservoirs of1000~1300m,1300~1600m,ought to adopt separately direct and indirect heating forms.Applied value method of time and fund,the heating schemes of crest un-modulation and crest modulation when geothermal heating with hot reservoirs of1000~1300m,1300~1600m have been evaluated,and correlation with current heating scheme of boiler,thereby the geothermal heating scheme of crest modulation has been optimized.Moreover,in the area both hot reservoirs of1000~1300m and1300~1600m are all exist,economical analyses on heating models in alone and joint of both hot reservoirs,showing that joint heating model better than the alone heating model clearly.
