现行的圈定地热储层的方法相当复杂,而且经常产生相互矛盾的结果。 最近,美国新墨西哥矿山工艺研究所的D.Norman和C.Bernhardt在研究与地热水有关的气体时,发明了一种估计地下热水温度的“地温计”,从而找到了一种勘查地热的新方法。 雨水和地表水含有大气圈中的气体,如氮气、氧气和氩气。随着雨水和地表水渗入地下温度不断上升,原来溶解于水的气体就被岩石和土壤中的气体(如氦
The current method of delineating geothermal reservoirs is quite complex and often produces conflicting results. Recently, D. Norman and C. Bernhardt of the Institute of Mines and Technology, New Mexico, in their study of geothermal water-related gases, invented a “geometer” that estimates the temperature of the underground hot water and found a geothermal new method. Rainwater and surface water contain gases in the atmosphere, such as nitrogen, oxygen and argon. As rain and surface water penetrate into the ground and temperatures continue to rise, the gas originally dissolved in water is replaced by gas in the rock and soil (such as helium
