Abstract

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.
