对 8个取自南海珠江口盆地XJ33-2 -1井的样品进行了热力学实验 ,使用电子自旋共振 (ESR)技术获取了样品中石英E′心天然状况下的ESR信号强度I1对经热活化技术处理后石英E′心的ESR信号强度I2 的比值。实验结果表明 :每个样品的活化温度不完全相同 ,这与母岩的特性有关 ;I1/I2 值与古地温呈正相关关系 ;I1/I2 值与地层年龄有很强的相关性 ,相关系数高达0 .99。说明I1/I2 值具有古地温指示和地质计时的实际意义。
Thermodynamic experiments were carried out on eight samples taken from well XJ33-2-1 of the Pearl River Mouth Basin in the South China Sea. ESR signal intensity I1 of the quartz E ’heart in the sample was obtained by electron spin resonance (ESR) The ratio of the ESR signal intensity I2 of quartz E ’heart treated by activation technique. The experimental results show that the activation temperature of each sample is not exactly the same, which is related to the characteristics of the parent rock. The I1 / I2 value has a positive correlation with the paleotemperature. The I1 / I2 value has a strong correlation with the age of the strata with a correlation coefficient up to 0 .99. This shows that the I1 / I2 value has the significance of paleo-geothermal indication and geological timing.
