摘要
目前国内的石油储备基地基本位于沿海地区,其泄漏后造成的土-水系统污染不容忽视。本文介绍了国内外众多学者关于石油类轻非水相液体(LNAPL)在含水土层中的运移及电阻率法监测最新研究成果,包括石油运移的物理试验模拟和数值模拟、静态污染土的电阻率特征、动态运移过程的电阻率监测。同时笔者预测特殊地质条件下石油的运移及重分布、石油污染后电阻率响应机制、油污染土电阻率的通用公式及国内对于多相流数值模拟软件的开发将成为今后研究的主要热点。
At present the domestic oil reserve bases are basically located in the coastal areas, and the soil-water system pollution after the leakage is not to be ignored. This paper introduced the latest research results about the migration of light non-aqueous phase liquid(LNAPL) such as petroleum in aquifers and the resistiv-ity monitoring methods by numerous scholars at home and abroad. It included physical experiments simulation and numerical simulation of petroleum migration, static resistivity characteristics of contaminated soil and dy-namic migration process monitoring by resistivity method. At the same time, the authors predict that petroleum migration and redistribution under special geological conditions, resistivity response mechanism after petroleum pollution, the general resistivity formula of oil contaminated soil, and the development of domestic multiphase flow numerical simulation software will become the future main research hot spots.
