郑州航空港区地热资源及开发利用

Development and utilization of geothermal resources in Zhengzhou airport area

郑州航空港区位于郑州市东南方向25 km,目前航空港区连接市区的供热管道没有贯通,港区供热是个亟待解决的问题。根据计算与评价结果,航空港区内浅层地热能较不适宜采用地下水换热方式开发,较适宜地埋管换热方式开发;深层地热新近系温热水主要分布在孟庄镇—龙王乡一线以东区域,热储层温度43℃—48℃,宜井深度500~1200 m,单井出水量15~20 m3/h;奥陶系—寒武系温热水主要分布在孟庄镇—龙王乡一线以西区域,热储层温度43℃—82℃,宜井深度1800~3000 m,单井出水量大于20~25 m3/h。对郑州航空港区地热资源进行开发利用,可有效解决港区目前的供热问题。

Zhengzhou airport area is 25 km in the southeast of Zhengzhou city.Heat supply pipe line here is not connected to that of the Zhouzhou city and the heat supply is the utgent problem.According to estimation and calculation the shallow geothermal energy in the airport area is suitable to develop with buried pipe heat transfer mode and not suitable with heat transfer mode.The deep Neogene mild hot water here is mainly distributed in the east area of the Mengzhuangtown-Longwang town line.Temperature of the geothermal reservoir is 43℃—48℃,the proper depth of wells 1800~3000 m and the single well discharge 15~20 m3/h.In the west area of the Mengzhuangtown-Longwang town line occurs Ordovician-Cambrian mild hot water with Temperature of the geothermal reservoir 20~25 m3/h and proper depth of wells 1800~3000 m and single well discharge 20~25 m3/h.Development and utilization of the the geothermal energy will effectively solve the heat supply problem of the airport area.
