温度梯度测井是近期发展起来的一种地球物理测井方法。尽管人门对温度的了解可以追溯到很早,但精确测定地球温度,是近期才开始的。而利用钻井温度梯度曲线进行地层相关性的解释,也仅有十几年的历史。钻井温度的测试工作是比较困难的,对测量仪器和测试方法要求很高。正常地温场 Temperature gradient logging is a recent development of geophysical logging methods. Although human knowledge of temperature can be traced back very early, the precise determination of the Earth’s temperature has only recently begun. However, the interpretation of stratigraphic correlation using the temperature gradient of drilling wells has only ten years of history. The testing of drilling temperature is more difficult and demanding on measuring instruments and testing methods. Normal temperature field
