摘要
给出了在２５０～１１００ＭＨｚ的频率范围内，利用自动网络分析仪，通过测量含岩石同轴线样品夹持器的散射参数，计算岩石介电常数的测量原理和测试方法。以大庆油田泥质砂岩的测量结果为基础，分析了岩石介电常数与频率、孔隙度、地层水矿化度、含水饱和度等影响因素之间的关系，并在１１００ＭＨｚ的频率下得出了大庆油田泥质砂岩介电常数的解释公式。
Abstract we describe the theory and means to use the network analyzer to measure the scat-tering parameters of the core samples in a coaxial-line sample holder and to calculate thedielectric constants of the core samples in the frequency range 250 to 1100 MHz. Basedon the measurement results of the rock samples from Daqing,the paper discusses the re-lationship of dielectric constants with the signal frequency,rock porosity,the salinity offormation water and water saturation, an accurate formula is proposed for Daqing Oil-field.SUBJECT TERMS:Daqing oil field,shaly sand,dielectric constant,scattering parame-ter,coaxial-line operator,porosity,salinity,water saturation
