摘要
在利用电阻率参数进行地热田勘查时,将电阻率参数转换为温度参数后形成的温度断面图能够更直观地显示地下温度场的分布情况;当勘查剖面有已知地热钻孔时,能够利用已知钻孔温度预测地下温度场的温度分布,这对判定热储构造分布、确定钻孔位置十分有利。温度计算时,地层电阻率初值的计算和勘查方法有关,选择正确的电阻率初值计算方法对温度计算结果至关重要。笔者对电阻率计算温度方法、地层电阻率初值计算方法进行了探讨,这对地热田勘查解释具有重要意义。
When the resistivity of the parameters is used in geothermal field exploration,the temperature sectional drawing made by the conversion of resistivity parameters to temperature paremeters is a more intuitive graph to show the distribution of underground temperature.When known geothermal drilling is available in the exploration profile,it is possible to use the known temperature drilling to forecast field distribution of the underground temperature,and this is advantageous to determining the distribution of thermal energy storage structure and the position of the drill hole.In temperature calculation,the calculation of initial formation resistivity is related to the surveying method.The choice of the correct calculation of initial resistivity is very important for temperature calculation results.This paper deals with the calculation method for temperature based on resistivity and initial resistivity value of strata,which is important in explaining the geothermal field exploration.
