Hydrochemistry characteristics of geothermal in Huangnigou Area of Penglai
摘要
Abstract
Based on water samples collected from the completed Huangnigou geothermal well and the surrounding shallow cold and hot water sources,this article conducts a water chemical characteristic analysis using methods such as Piper trilinear diagram,ion ratio analysis,Langelier-Ludwig diagram,silica-enthalpy model analysis,corrosivity evaluation,and water-rock interaction simulation.Cation and silica geothermometers were applied to estimate the geothermal reservoir temperature.The results indicate that the Huangnigou geothermal water has a temperature of 56℃ and is classified as the HCO3·SO4-Na type with weakly alkaline.It shows relatively high concentrations of fluoride and metasilicic acid,reaching or approaching levels of medicinal value,and can thus be classified as fluoride-rich fresh water.The water is non-corrosive and non-scaling,suitable for use in health care and rehabilitation services.Analysis suggests possible mixing with cold groundwater at an estimated cold-water mixing ratio of 22.5％.The Huangnigou geothermal water belongs to partially equilibrated water,with undersaturated quartz and chalcedony and calculated geothermal reservoir temperature ranges from 61.8 to 74.0℃.This study of the hydrochemical characteristics of the Huangnigou geothermal water provides an important basis for future exploration of geothermal resources in this area,and offers data support for well-site selection and utilization planning.关键词
