测井电缆的分布参数,对于电信号传播规律的分析有着重要的意义。但是,工业上使用的电缆,生产厂家不提供分布参数。本文根据有关理论公式和观测数据对测井电缆分布参数怍了初步估算,抛砖引玉,希望读者给予补充和指正。所谓测井电缆分布参数是指:(1)分布电容 C_0=△C/△X;(2)分布电感 L_0=△L/△X;(3)分布电阻R_0=△R/△X;(4)分布漏电电阻R_0′=△R′/△X。这些分布参数又分两
Logging cable distribution parameters for the analysis of the propagation of electrical signals is of great significance. However, cables used in industry, manufacturers do not provide distribution parameters. In this paper, according to the theoretical formula and observation data on the distribution of logging cable parameters of a preliminary estimate, initiate, hope readers to supplement and correction. The so-called distribution of logging cable parameters are: (1) distributed capacitance C_0 = △ C / △ X; (2) distributed inductance L_0 = △ L / △ X; (3) distributed resistance R_0 = △ R / △ X; ) Distribution of leakage resistance R_0 ’= △ R’ / △ X. These distribution parameters are divided in two
