东营市城区馆陶组热储回灌性能分析

Analysis on Recharge Property of Guantao Geothermal Reservior in Dongying City

摘要:

东营市城区馆陶组热储为新近系松散碎屑岩层状热储，目前地热资源开采量约95万m3/a，回灌是解决热储压力下降与地热尾水排放对环境造成不良影响的最佳措施，该文采用自然回灌试验方法探讨回灌条件下馆陶组热储的渗透性能，并与德州市城区馆陶组热储压力回灌试验成果进行了对比，对该热储的回灌性能进行了分析，为指导该区地热回灌提供了科学依据。

Abstract:

Guantao geothermal reservior in Dongying city is Neogene fragemental sedimentary geothermal reservior. Its extraction of geothermal resources is about 95m3/a at present. Recharge is the best way to solute the pressure drawdown in the reservior and environmental pollution. In this paper, penetration performacne of Guantao geothermal reservior under the recharge condition is discussed, the results are compared with the pressurized reinjection experiment in Guantao geothermal reservoir in Dezhou city, and the recharge property of this geothermal reservoir is analyzed as well. It will provide a scientific basis for geothermal recharge in this area.
