东营市中心城区地热田地热回灌可行性分析

Feasibility Analysis on Geothermal Recharge of Geothermal Field in Central District of Dongying City

摘要:

利用东营市中心城区鲁班公寓的地热生产井，对新近纪馆陶组和古近纪东营组热储层进行了自然压力条件下的异层和同层回灌试验。结果表明，回灌量与水头升高呈正相关关系，单位回灌量与水头升高呈负相关关系，馆陶组东热2井回灌能力为东营组东热5井的3倍左右。通过对该地热田热储地质条件、回灌能力及地热水开采潜力的分析，认为目前条件下东营城区还不适宜全面推行地热回灌。
