中文摘要:可持续回灌是地热资源循环采用的基本。本文通过热储敏感性、堵塞原因、成井结构以及地面装置分析了回灌衰减的原因。认为物理堵塞是回灌堵塞的主要原因,成井结构是维持可持续回灌的关键,标准的地面设备可避免由于物理和化学原因引起的堵塞。本文采用成功的成井结构和标准的地面装置开展馆陶组热储回灌地热资源循环采用的示范工程建设,回灌率达到100~123 m3/h,实现了天津滨海新区馆陶组热储回灌突破,保证了滨海新区馆陶组地热资源循环利用。

A STUDY ON THE RECYCLING UTILIZATION OF GEOTHERMAL RESOURCES IN BINHAI NEW AREA, TIANJIN——STUDY AND DEMONSTRATION OF THERMAL STORAGE AND REINJECTION TECHNOLOGY OF GUANTAO RESERVOIR
Abstract:Sustainable reinjection is the basis of geothermal resource recycling. The reason of reinjection decrease is summarized through the analysis of reservoir sensitivity, blocking factors, well completion structure and ground installation, in which it is believed that physical blocking is the main cause of reinjection blocking. The well completion structure is the key to keep sustainable reinjection, while standard ground equipment can help avoiding blocking caused by physical and chemical reasons. In this article, successful well completion construction and standard ground installation are applied to the demonstration project construction of geothermal resources recycling of thermal storage and reinjection of Guantao Reservoir, and the reinjection rate is 100~123 m3/h, which is a breakthrough of thermal storage and reinjection of Guantao Reservoir and guarantees the recycling of geothermal resources of Guantao Reservoir in Binhai New Area, Tianjin.
