The use of electrochemical effects in petroleum exploration and engineering–geological applications is discussed with reference to the Zhirnovsky oil and gas field where mobile forms of metals are 1.5–2 times above the background. Electrochemical stiffening applied to Maastrichtian shales, which are sliding planes of landslides in the Lower Volga area, increased their stiffness by a factor of 2 or more. 相似文献

Electrokinetic flows include the migration of fluid, chemicals, fine particles, bacteria, and electrons through a soil–fluid–chemical system driven by an externally applied direct-current (d.c.) electric field. The promising potential of electrokinetic remediation of contaminated fine-grained soils has stimulated recent interest in the study of electrokinetic flow processes, in particular the impact of a prolonged application of a d.c. electric field on fine-grained soils. The results of a bench-scale laboratory experimental investigation on some of the fundamental aspects of prolonged electrokinetic flows in kaolinites, including gas generation rates at power electrodes, electrochemical behaviour of the soil–fluid–chemical system, time variation of electric current intensity flowing through the soil, pH gradient development in the soil, effects of reservoir chemistry on electro-osmotic fluid volume flow rate and flow direction through the soil, time variation of electro-osmotic volume flow rate, and energy requirements per unit volume of fluid transported, are presented in this paper. Effects of soil type and pore fluid chemistry on these aspects were also studied. 相似文献

志留系地层是桂东南博白―岑溪地区铅锌矿床的主要赋矿层位,产出佛子冲和东桃等层状铅锌矿床,其直接赋矿围岩均为下志留统碎屑岩地层中的层状绿色岩和碳酸盐岩夹层。碳、氧同位素测试结果显示,赋矿层位中碳酸盐岩夹层的δ18 O值显著低于正常海相灰岩,在δ18 O-δ13 C图解上碳酸盐岩夹层和矿石中方解石样品投点均集中分布在基性-超基性岩浆岩和花岗岩区及附近。该碳酸盐岩夹层的形成与海底热水沉积作用有关,类似于现代海底烟囱中的低温喷口产物。桂东南志留纪热水沉积成矿作用可以概括为电解成矿机制。 相似文献
