Operation level evaluation system and indicators in the middle and deep geothermal heating projects

Abstract

In order to continuously improve the operation level and profitability of middle and deep geothermal heating projects, it is necessary to establish a set of systematic and comprehensive evaluation methods and indicators for operation effects. This paper will be evaluated on the basis of systematic, normative and practical principles. However, the results of the effect evaluation are multiple and multilevel. This paper will also be based on the characteristics of middle and deep geothermal heating projects. So it will establish a set of evaluation index system for the benefit of deep geothermal heating engineering, combining technical and management indexes, economic and non-economic indexes. It has determined 3 aspects and 10 evaluation indicators in technical level, management level and economic benefits. Therefore the analysis of the specific operation project shows that the evaluation method and index are in line with the reality, and the operation level of the project is quantified. In addition, it also puts forward specific improvement directions which can effectively guide the improvement of operation level and efficiency of middle-deep geothermal heating projects.
