摘要: 总结了鲁32井水温正常动态特征以及自然环境干扰形态特征,探究鲁32井水温异常变化特征,通过对该井周围500km范围内中等地震及远场大震发生时间、空间与水温异常时段对比,发现两者对应关系良好,综合分析已有数据资料认为,鲁32井水温存在附加地热场异常变化的构造条件,可作为近场中等地震前兆异常和远场大震前兆异常中短期判别指标之一。Abstract: Normal dynamic characteristics and natural environment interference characteristics of the water temperature in Lu-32 well are summary in this paper.To explore well water temperature anomaly variation characteristics,medium earthquake within the range of 500 km from the well and far field great earthquakes are contrasted including their occurring time,space and water temperature anomalies,and it is found that there are good corresponding relations.Comprehensive analysis of existing data shows that there are additional tectonic conditions of temperature geothermal field changes of the well temperature,which can be used as one of discriminant index for precursory anomaly of near-field medium earthquakes and mediumshort-term precursory anomaly of far-field great earthquakes.
