摘　　要：通过对江苏区域内12口地震研究水温观测井,测量井孔不同深度温度背景值,计算温度梯度;结合温度变化与井孔的地质构造,对比分析研究区内井孔水温特点。结果表明:水温梯度是水-热动力学与地热动力学综合影响的结果,井孔地质构造、含水层分布对温度梯度值存在重要影响。该研究结果可为井孔水温定量分析提供数据支撑。The temperature gradient was calculated by measuring the temperature background values at different depths of 12 boreholes for seismic research in Jiangsu Province.Combined with the temperature change and the geological structure of the borehole,the characteristics of borehole water temperature in the study area are compared and analyzed.The result shows that the temperature gradient of the borehole is the result of the combined effect of the combined mechanism of hydrothermal dynamics and geothermal dynamics.The borehole geological structure and the distribution of aquifer have an important influence on the temperature gradient value.The research results can provide data support for quantitative analysis of wellbore water temperature.
