视电阻率测井数据处理的应用研究

The Application Research of Apparent Resistivity Logging Data Processing

影响土的电阻率的因素众多,土的视电阻率大小与土的工程力学指标密切相关。在阐述视电阻率测井基本原理的基础上,采用三极测深的方式采集数据,对比分析所测得的三种类型土的视电阻率值,并结合土工试验结果,依据试验数据归纳总结出亦庄地区典型土的电阻率值与土的饱和度、含水率、天然密度之间的相关性。当土体趋于饱和时,土的视电阻率趋于稳定,约等于水的视电阻率,土体视电阻率值随着含水率增大而减小,而随着天然密度的增大而增大。

There are many factors to affect the electrical resistivity of the soil. The electrical resistivity of the soil is closely related to the geotechnical parameters of the soil. This paper is based on expatiating upon the basic theory of the apparent electrical resistivity. A three-sounding way of measuring data acquisition , by contrasting and analyzing the apparent electrical resistivity of three types soil, and combining the results of the soil testing, the article summarizes the relativity between the apparent electrical resistivity of the soil in the Yizhuang area and three elements such as saturation, water content, natural density. It is proved that when the soil becomes saturated, the resistivity of the soil is stabilized, about the resistance of water, soil resistivity value increases with the moisture content decreases, and it increases with the density of natural increase.
