【摘要】：中國是世界上地?zé)豳Y源非常豐富的國家之一,廣泛分布著高溫、中低溫地?zé)�。相較于高溫地?zé)豳Y源而言,中低溫地?zé)豳Y源有著分布范圍更廣、區(qū)域面積更大,開發(fā)利用條件較高的特點(diǎn)。隨著近些年我國經(jīng)濟(jì)的發(fā)展,傳統(tǒng)能源的日趨短缺導(dǎo)致對清潔能源的需求量日益迫切,因而中低溫地?zé)豳Y源的開發(fā)和利用受到了愈來愈多的關(guān)注。而開展中低溫地?zé)豳Y源中地下熱水組分含量和分布特點(diǎn)以及演化特征和熱水圍巖之間的相互作用等基礎(chǔ)性研究,對中低溫地?zé)嵯到y(tǒng)的成因和地?zé)豳Y源的開發(fā)利用具有重要的指導(dǎo)作用。本文對贛南地區(qū)氮?dú)庑蜏厝瘜W(xué)組分和氫氧同位素特征進(jìn)行了分析,簡要探討了溫泉水化學(xué)組分特征,計算了溫泉的補(bǔ)給高程,海拔范圍在840m-1100m之間。著重研究了氮?dú)庑蜏厝妮^高pH值和硫酸鹽、碳酸鹽之間的復(fù)雜關(guān)系,并使用水文地球化學(xué)模擬軟件PHREEQC2.15及數(shù)據(jù)庫wateq4f.dat計算了熱水中部分次生礦物飽和指數(shù),探究了氮?dú)庑蜏厝c次生礦物組分(如碳酸鹽,氟化物等)之間的平衡狀態(tài)。初步探討了溫泉熱水系統(tǒng)中存在強(qiáng)烈而持續(xù)的水-巖相互作用,但地下熱水TDS仍較低的原因,即地下熱水系統(tǒng)保持著‘沉淀-溶解’的相對動態(tài)平衡。計算并估算了溫泉的熱儲溫度。結(jié)果表明,氮?dú)庑蜏厝獰醿囟确秶鸀?0℃—120℃,溫泉具有較大的熱儲深度,范圍在2800m-4400m之間。最后,以研究區(qū)內(nèi)水溫最高的汝城熱水溫泉為典型特例,從“點(diǎn)”的角度初步探討了贛南地區(qū)溫泉成因模式。為江西省贛南地區(qū)含氮溫泉和地?zé)豳Y源的未來規(guī)劃和利用提供參考依據(jù)。
[Abstract]:China is one of the countries with abundant geothermal resources in the world. It is widely distributed with high temperature and moderate and low temperature geothermal resources. Compared with high temperature geothermal resources, medium and low temperature geothermal resources have a wider distribution range and larger regional area. With the development of our economy in recent years, the shortage of traditional energy sources leads to the increasingly urgent demand for clean energy. Therefore, more and more attention has been paid to the exploitation and utilization of medium-low temperature geothermal resources. In this paper, the chemical composition and hydrogen oxygen isotope characteristics of nitrogen type hot spring water in south Jiangxi are analyzed, and the chemical composition characteristics of hot spring water are discussed briefly. The recharge elevation of the hot spring is calculated, and the elevation range is between 840m-1100m. The complex relationship between the higher pH value of the nitrogen hot spring and the sulfate and carbonate is studied. The saturation index of some secondary minerals in hot water is calculated by using hydrogeochemical simulation software PHREEQC2.15 and database wateq4f.dat, and the composition of nitrogen type hot springs and secondary minerals (such as carbonate) is explored. The reason why there is strong and continuous water-rock interaction in hot spring hot water system is discussed, but the TDS of underground hot water is still low. The thermal storage temperature of hot spring is calculated and estimated. The results show that the thermal storage temperature of nitrogen type hot spring is between 80 鈩，
