Geothermal Rational Exploration and Exploitation Strategy Research in Beijing

Abstract

Based on the analysis of geothermal research and utilization, this paper lists the most main challenges of geothermal exploration and exploitation at present in Beijing which is including the lack of regional reconnaissance, the undeveloped of prospecting techniques, the shortened of service life in those geothermal fields which are exploited unreasonably, the unsystematic of dynamic monitoring, and etc. Therefore, for making rational utilization and effective protection of geothermal resources finally come true, the paper suggests a strategy research, namely to set up large scale geothermal investigation which will be carried out in the whole Beijing for making clear all the geothermal conditions; to point out geothermal exploitation target areas; to assess exploration methods for reducing drilling risks; to study reinjection techniques and to establish critical mode making the equilibrium between extraction and reinjection in typical geothermal field; to build structural models and matching numerical simulation models for predicting utilization effect of geothermal system; and to construct geothermal data base and management information system for managing the exploration and utilization of geothermal field timely and effectively.
