摘要
为定量评价目标区域中深层水热型地热资源品质,以沉积盆地内中深层水热型地热资源为研究对象,以地热资源品质评价为主要内容,深入分析地热地质条件、地热资源量和地热流体质量3个部分。选择对地热资源影响较大的16项指标,使用层次分析法对每项指标进行权重赋值,将中深层水热型地热资源划分为三级7类。Ⅰ级区域为资源优势区,可进行高效开发;Ⅱ级区域为资源富集区,满足工业开发要求;Ⅲ级区域为资源不富集区,最终形成一套可量化评价的资源评价体系,为地热资源是否可进行利用提供数据分析结论。通过河北省唐山市曹妃甸区地热供暖项目的实际应用效果作为案例,验证了评价体系的针对性、实用性。
To quantitatively assess the quality of deep hydrothermal geothermal resources in the target area,with a focus on middle deep hydrothermal resources in sedimentary basins,a comprehensive analysis is conducted.This analysis delves into the effects of geothermal geological conditions,the nature of the geothermal resources themselves,and the quality of geothermal fluids on the overall resource quality.For this assessment,sixteen indicators that significantly impact the quality of geothermal resources are identified.These indicators are then incorporated into an Analytic Hierarchy Process(AHP)framework,which assigns weights to each indicator,facilitating a quantitative evaluation.The middle-deep hydrothermal geothermal resources are divided into three levels and seven categories.LevelⅠareas are resource advantage areas that can be efficiently developed;LevelⅡareas are resource rich areas that meet the requirements of industrial development;LevelⅢareas are resource non enriched areas.Ultimately,a quantifiable resource evaluation system is formed to provide data analysis conclusions on whether geothermal resources can be utilized.The relevance and practicality of this evaluation system are demonstrated through its application in a case study.The example of geothermal development and usage in the Caofeidian District of Tangshan City,Hebei Province,serves as a testament to the system's effectiveness in guiding decision-making processes for geothermal resource utilization.
