摘要
用Gouy法测定了原油和油田水的磁化率,证实它们都是抗磁性物质。原油和油田水类型不同,磁化率也不同。在原油中,含蜡油的磁化率小于稠油。含蜡油的磁化率与凝固点有关,凝固点越高,磁化率越小;稠油的磁化率与粘度有关,粘度越高,磁化率越大。在油田水中,地面水的磁化率小于回注污水和油井水的磁化率。测定结果表明,磁处理效果与磁介质的磁化率有关。磁化率绝对值越大,磁处理效果越好。
The magnetic susceptibility of crude oil and oilfield water measured by Gouy method.The results confirm that they are all diamagnetic substances.Different kinds of crude oil and oilfield water have different values of magnetic susceptibility.The magnetic susceptibility of wax-containing crude oil is smaller than that of viscous crude oil.The.magnetic susceptibility of wax-containing crude oil is related to the solidifying point.The higher the solidifying point,the smaller the magnetic susceptibility.The magnetic susceptibility of viscous crude oil is related to the viscosity.The higher the viscosity,the greater the.magnetic susceptibility.The magnetic susceptibility of surface water is smaller than that of reinjected water and produced water.It was shown that the effects of magnetic treatments are related to the-magnetie susceptibility.The higher the absolute values of magnetic susceptibility,the better the effects of magnetic treatments.
