Temperature logs recorded shortly after drilling operations can be the only temperature information from deep wells. However, these measurements are still influenced by the thermal disturbance caused by drilling and therefore do not represent true rock temperatures. The magnitude of the thermal disturbance is dependent on many factors such as drilling time, logging procedure or mud temperature. However, often old well reports lack this crucial information so that conventional corrections on temperature logs cannot be performed. This impedes the re-evaluation of well data for new exploration purposes, e.g. for geothermal resources. This study presents a new method to correct log temperatures in low-enthalpy play types which only requires a knowledge of the final depth of the well as an input parameter. The method was developed and verified using existing well data from an intracratonic sedimentary basin, the eastern part of the North German Basin. It can be transferred to other basins with little or no adjustment.

修正低焓区温度对数曲线的新方法

钻探操作后不久记录的温度记录可能是来自深井的唯一温度信息。但是，这些测量值仍然受钻井引起的热干扰的影响，因此不能代表真实的岩石温度。热干扰的大小取决于许多因素，例如钻井时间，测井程序或泥浆温度。但是，通常老的井报告缺少此关键信息，因此无法对温度测井进行常规校正。这阻碍了为新勘探目的（例如地热资源）而对井数据进行重新评估。这项研究提出了一种校正低焓游隙类型测井温度的新方法，该方法仅需要知道最终的井深以及输入参数即可。该方法是根据北德意志盆地东部克拉通沉积盆地的现有钻井数据开发和验证的。几乎无需调整即可将其转移到其他盆地。
