Geoenergy Potential Map of the City of Turku Grid Chart

The study carried out in 2016 is mainly based on GTK’s existing geological spatial datasets and research reports. In addition to these, drilling data of the subscribers’ technical operation, data on drilled energy wells and the thickness of the drilling sections of the energy wells carried out in the area were also used to specify the area’s land cover thickness data. The work also included field surveys and examination of old drilling samples. The geoenergy potential map cannot be used as such to dimension the energy wells or well fields of properties, because the map is always a generalised presentation regardless of the accuracy. The map does not show groundwater areas, water abstraction shelters – with their areas, nature conservation – areas, underground structures and other territorial reserves that may restrict the use of geoenergy.本研究于2016年实施，主要依托GTK现有的地质空间数据集与研究报告。除此以外，本次研究还纳入了用户方技术作业的钻井数据、区域内已施工的能源钻井数据以及能源钻井钻进段的厚度数据，用于明确该区域的地表覆盖厚度参数。本次工作还涵盖了野外调查与旧钻井样品的检验分析。 该地热能潜力地图不可直接用于确定能源钻井或相关地块钻井区块的规模，因为无论精度如何，该地图均为概化呈现成果。该地图未标注地下水区域、取水防护带（含其管控范围）、自然保护区、地下构筑物以及其他可能限制地热能开发利用的地域性保护预留区域。
