摘要
对盘锦地震台红25井和于105井水温梯度进行精密测量并对水温梯度特征进行分析。结果表明,观测井不同深度上的水温变化形态有一定的相似性,水温稳定过程均呈对数曲线变化,且两口井水温梯度曲线变化具有一致性特征,其温度—深度曲线几乎重合,但井孔不同深度的井水温度微动态特征明显,显示出一定的差异性。结合井孔柱状图与区域水文地质资料综合分析认为,差异性变化主要与井孔的水文地质特征、地下水类型有关。根据对井孔水温梯度数据的分析确定了水温探头投放的最佳位置。
A file for Panjin seismic Hong 25 wells and the well water temperature gradient in Yu 105 precision measurement and analysis the characteristic of temperature gradient.The results show that,Observation well water temperature in different depth change form has a certain similarity,Water temperature stable process a logarithmic curve changes,Two wells water temperature gradient curve and has the characteristics of consistency,Its temperature depth curve almost overlap,but different depth hole section of well water temperature dynamic characteristics significantly,showing a certain difference.Combined with the well bore log chart and regional hydrogeology data comprehensive analysis think,difference change main hydrogeological characteristics、groundwater with hole type.According to the analysis of borehole water temperature probe into the best position.
