物探测井技术在地热开发勘探中的应用研究

依据物理温度场特点，即使是地下变态温场，低温指向高温逐渐收缩趋向热水通道或加热源（热源、热异常中心）的规律是一样的。温度场反映了热田地下空间形态。本文以西藏羊八井浅层热田温度测井为例，通过正确选择剖面，研究分析热田地热场的平面特征和剖面特征．从井间温度测井曲线反演，阐述了一种建立热场模型的方法。同时探讨了羊八井热田地热场在该区的地质、水文意义，指出研究井温曲线的各种形态，有助于分析地质构造、追溯热流体运移、迳流路径，为合理布孔提供科学依据。

THE APPLICATION STUDY OF GEOPHYSICAL WELL LOGGING IN GEOTHERMAL SURVEY

Based on the character of the physical temperature field,even if the dynamic temperature field underground ,the lower temperature leads to the higher temperature and gradually shrink to tend to the thermal path or thermal origin as well. So,temperature field reflects the form of geothermal fields undergrond. Taking the shallow temperature logging of Yangbajing geothermal power station in tibet as a example, a method setting up the model of geothermal field is described in this paper by selecting suitable profiles, analyzing the plan characters and profile characters, reversing temperature logging curves among wells. Meanwhile,the paper discusses the meaning of hydrogeology of Yangbajing geothermal fields and points out that studying the forms of temperature logging curves is a good help to analyze geological structures, back to the trails of hot flow, and provode scientific basics to distribute trill holes reasonably.
