平凉深井地电阻率与地层温度关系的研究

摘要

At first, briefly introduced the deep well observation system in Pingliang seismic station. Secondly, the correlation analysis, regression analysis and other methods were used to study the ob-servational data of earth resistivity and formation temperature in underground well at Pingliang sta-tion.Results showed that:positive correlation was between shallow ground temperature and earth re-sistivity, and it performed for a fixed period specification change. Finally, the relationship between configurations of earth resistivity observation device and shallow ground influence factor was dis-cussed.The method and theory can be used as an effective reference when the earth resistivity obser-vation system was changed to the underground observation or newly build a deep well observation system, and it can play the role of rational use of resources and saving construction costs.%首先介绍平凉台深井观测系统,其次采用相关分析、回归分析等方法对平凉深井地电阻率和地温观测资料进行研究.结果表明:浅层地温与地电阻率为正相关,表现为固定周期形态变化的关系.讨论了地电阻率观测装置与地表影响因子的关系,当地面电阻率观测系统改为井下观测或新建深井观测系统时,该方法和理论可以作为一个有效的参考,起到合理利用资源,节约建设成本的作用.
