| 摘 要： | 本文给出了在实验室用同轴测量线装置测得的沉积岩岩石样品的介电常数,分析了取自胜利油田的三类岩石样品的测量结果。讨论了岩石介电常数与频率、孔隙度、孔隙水的矿化度等的关系,提出对不同岩石类别应取的介电常数值,给出了计算孔隙度公式。所得出的结论对电磁波传播测井曲线的解释和电磁波传播测井仪器的设计有一定意义。

| Abstract: | The dielectric constants of sedimentary rock specimen measured with coaxial slotted line unit are given in this paper. The measurement results of rock specimens from Shengli oilfield are analyzed.The relatipnship of dielectric constants with frequency, porosity of the rock and salinity of pore water is discussed. The proper dielectric constants for different kinds of rocks are proposed. The formula for determining porosity by dielectric constant measurement of rock samples from Shengli oilfield is given.The conclusion of the paper will be useful for EPT interpretation and logging tool design. |
