中文摘要
形成非火山岩泰国地热水的热源、水循环系统和热交换机制是亟待解决的问题。主要研究成果如下:(1)在花岗岩区外发现了高氦同位素异常。(2)伽马能谱在地热勘探中具有良好的应用前景。(3)第四纪玄武岩岩浆房小而深,但有些岩浆室年轻,足以供热。(4)花岗岩的生热范围为8-18HGU。这相当于在3-5千米的深度获得300゚C。(5)外部温泉区的蚀变年龄较老。这表明火山地热系统的热液活动已经持续了很长时间。(6)钻井岩心流体包裹体均一温度与实测值基本一致。(7)浅层油藏的计算机模拟显示了8610年后的流态变化。
英文摘要
The heat source, water circulation system and heat exchange mechanism to form non-volcanic Thai geothermal waters are problems to be solved. Following are results of our study.(1) High heliun isotope anomalies are found outside of granitic area. (2) Gamma ray spectrometry is good for geothermal exploration. (3) Magma chamber of the Quaternary basalt is small and deep but some of them are youg enough to supply heat. (4) Heat generation from granitic rocks are range from 8-18 HGU. It corresponds to get 300゚C at the depth of 3-5km. (5) Alteration ages of outside hot spring areas are relatively old. It indicates that the hydrothermal activity of volcanic geothermal systems had been continued long time. (6) Fluid inclusion homogenized temperatures of drilling core are almost same as measured ones. (7) Computmodeling of shallow reservoir shows the change of flow patterns until after 8610 years.
