一、用电化学方法堵漏电化学方法,就是用直流电在钻孔中造成人工电场,以引起孔壁岩石物理化学和机械性质的变化。物理化学变化中包括电解、电渗和电泳现象。电解时,产生物质分解作用和离子的转换,这是岩石性质改变的基础。溶液中电解质的扩散,使土层颗粒表面产生物理化学性质变化,引起新的粘结物质(钙、镁、硅酸)及新矿物(方解石、石膏、褐铁 First, electrochemical methods plugging electrochemical method is to use DC to create artificial electric field in the borehole to cause pore rock petrophysical and mechanical properties change. Physical and chemical changes include electrolysis, electroosmosis and electrophoresis. Electrolysis, resulting in material decomposition and ion conversion, which is the basis for the change of rock properties. Electrolyte diffusion in solution causes the physical and chemical properties of the soil particles to change, causing new binding substances (calcium, magnesium, silicic acid) and new minerals (calcite, gypsum,
