岩石介电常数是由固体、液体、气体组成的多相体系,其大小取决于组成岩石的各种物质的性质、含量以及分布状态,还与电场频率、温度、压力等外界因素有关。研究岩石介电常数与各种影响因素的关系,对电磁波测井(如相位介电测井)是非常重要的。本文以大庆地区岩样的实验为基础,结合国外资料,分析岩石介电常数与各种影响因素的关系。
Rock dielectric constant is a heterogeneous system composed of solid, liquid and gas. Its size depends on the nature, content and distribution of various substances that make up the rock. It is also related to external factors such as electric field frequency, temperature and pressure. Studying the relationship between rock dielectric constant and various influencing factors is very important for electromagnetic wave logging, such as phase dielectric logging. Based on the experiments of rock samples in Daqing area, this paper analyzes the relationship between rock dielectric constant and various influencing factors based on foreign data.
