Quality Evaluation of Geothermal Fluid in the Lindian Area of the Songliao Basin

The quality of geothermal fluids determines their direction of use, and in the past, the evaluation of geothermal fluid quality mainly focused on single well evaluation or local area evaluation. This article uses 5 pieces of geothermal water chemistry data to conduct quality evaluation of geothermal fluids in the Lindian area, mainly including medical thermal mineral water quality evaluation, drinking mineral water evaluation, domestic drinking water evaluation, fishery water evaluation, agricultural irrigation water evaluation, and geothermal fluid corrosiveness and scaling tendency evaluation. The evaluation results show that the geothermal wells in the study area are not suitable for developing drinking mineral water; Not suitable as drinking water for daily use; It cannot be directly used as irrigation water evaluation; Suitable for medical hot mineral water development and aquaculture; Geothermal fluids are all non-corrosive water with minimal fouling, and can be used for geothermal heating after treatment.
