摘要
从磁处理对垢溶解度、粘土膨胀、油水界面张力、机械杂质含量和细菌繁殖抑制等方面的影响研究了磁增注机理.研究表明,磁处理可提高某些垢的溶解度,抑制粘土膨胀,减少机械杂质含量,因此有利于提高注入水量.磁处理虽可降低油水界面张力,但降低幅度很小,不起主要作用.细菌试验证实,在通常条件下,磁处理对细菌繁殖无抑制作用.
This paper studies the mechanism of magnetic stimulation in injection well and analyzes the effect of magnetic treatment on the solubility of scales, clays welling, the interfacial tension of oil and water, the content of mechanical impurities and the inhibition of bacterial growth. The result shows that magnetic treatment can improve the solubility of some scales, inhibite clays welling and reduce the content of mechanical impurities. So the injectivity of injected water can be increased with the method. The tests confirm that depression of interfacial tension of oil-water by magnetic treatement is low because of oil blocking. Magnetic treatment has no effect on bacterial growth.
