摘要
通过饱和多孔岩石的低频亚共振试验 ,得到了饱和多孔岩石的内耗峰是典型的弛豫峰的结论 .不同的饱和液体、不同的岩石导致不同的弛豫峰特征 ,饱和岩石的弛豫特性 ,是寻找油田、地热田和预测储层的物性基础 .试验结果表明 ,饱和多孔岩石都具有一个共同的特性———时间和温度的等效性 ,即降低温度与增加振动频率是等效的 ,这就是饱和多孔岩石的弛豫共性 .
From the experiments of low frequency sub resonance vibration for different fluid saturated rocks, the internal friction peak was found to be a typical relaxation peak. Different saturating fluid and different rocks lead to different characteristics of relaxation peak which can be physical basis to find oil field and geothermal field, and to predict the oil layers. Analysis of experimental results confirm that the rising of temperature is equivalent to the reducing the frequency. The time temperature equivalence is a commonness of saturated porous rocks. [
