摘　　要：高滩温泉RJ2井施工时遇多层含水结构,热矿水具有浅部溶蚀裂隙次生热储层温水水量较丰富、深部构造裂隙热储带较高温热水水量偏小的赋存特征。成井施工时除对浅部常温水进行封隔外,还在温水含水段创造性地设计安装井内活动取水装置,实现温水控量取水与下部较高温热水混合,获得水量、水温均满足合同要求的热矿水资源,达到保质增产的理想成井效果。RJ2井的保质增产措施在对流型低温地热系统的中浅地热井施工时,在相似工况条件下具有一定的适用性,可以参考使用以提高资源利用率和经济效益。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.
