Utilization State and Protection Project in Tianjin Geothermal Area

Abstract

This report is based on exploitation and utilization data of geothermal resources in Tianjin, and is aimed at the existing problems such as the lack of a unified plan, low utilization ratios and low reinjection ratios. Several counter measures are put forward, which include subarea management, gross control, intensity control, utilization mode control and distribution optimization. According to the measures, the geothermal area is divided into 4 types: confined exploitation zone, controlled exploitation zone, encouraged exploitation zone and exploring zone. Then some respective protective aims and measures are carried out for the sustained exploitation and utilization of geothermal resources.
