摘　　要：THD(Take Hot Drilling)是一种创新的专利技术,意为钻井取热,该专利是一种在地热开采中有效提高产水量及保持温度的多通道系统,该多通道系统有效地增加了产水量,其核心思想是将不符合温度要求的多个含水层的水资源充分利用。这一技术通过引导这些水资源至井底,然后借助井壁进行加热升温,并与地下高温热水混合,最终通过出水通道将其抽出,该出水通道具备隔热保温的功能,有效减少地热水向地面输送的沿程温度损失,从而实现了保持温度和提升的双重目标。首次在某地热井中应用THD专利技术证实了该系统在提高地热开采效率方面的可靠性和有效性。此外,在出水通道方面仍存在改进和优化的潜力,有待进一步深度研究与分析探讨。总的来说,THD专利技术为地热(温泉)井开采提供了一项重要的技术保障手段,值得进一步验证和广泛推广应用。THD(Take Hot Drilling)is an innovative patented technology that means drilling for heat.The patent is a multi-channel system for effectively improving water production and water production temperature in geothermal exploitation.The multi-channel system effectively increases water production,and its core idea is to make full use of water resources from multiple aquifers that do not meet temperature requirements.This technology guides the water to the bottom of the well,where it is heated by the wall,mixed with hot water underground,and finally pumped out through the outlet.The outlet channel has the function of heat insulation and heat preservation,which effectively reduces the temperature loss along the way of geothermal water conveying to the ground,thus realizing the dual goals of temperature increase and production increase.The application of THD patented technology in a geothermal well has demonstrated the reliability and effectiveness of the THD system in improving the efficiency of geothermal extraction.In addition,there is still potential for improvement and optimization in the outlet channel,which needs further in-depth research and analysis.In general,THD patented technology provides an important technical guarantee means for geothermal(hot spring)well mining,which is worthy of further verification and widespread application.
