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. The effects of magnetic treatment on scale solubility, clay swelling, oil-water interfacial tension, mechanical impurity content and inhibition of bacterial growth were investigated. The results show that magnetic treatment can increase the solubility of some scale, inhibit the swelling of clay and reduce Mechanical impurities, and therefore help to increase the amount of injected water.Although the magnetic treatment can reduce the oil-water interfacial tension, but the decrease is small, can not play a major role.A bacterial test confirmed that under normal conditions, magnetic treatment has no inhibitory effect on bacterial growth.
