The occurrence characteristics of thermomineral water and innovation in the application of quality assurance and stimulation measures in Gaotan Hot Spring RJ2 Well
During the construction of Gaotan Hot Spring RJ2 Well,the hot mineral water is abundant in warm water in shallow dissolution fissure secondary hot reservoir and small in high temperature hot water in deep structural fissure hot reservoir.In addition to sealing off the shallow normal temperature water in the well construction,the well mobile water intake device is also creatively designed and installed in the warm water water-containing section to realize the mixture of warm water intake and lower high-temperature hot water,so as to obtain thermomineral water resources with water quantity and water temperature meeting the requirements of the contract,and to achieve the ideal well completion effect of maintaining the quality and increasing the production.The quality assurance and stimulation measures of RJ2 Well have some applicability in the construction of medium and shallow geothermal wells in convective low-temperature geothermal systems under similar working conditions,and can be used for reference to improve resource utilization and economic benefits.
