永磁技术已广泛地应用于医学、工业和农业等领域。近几年,磁化技术在石油工业中的应用日趋广泛、多数集中在水的增注、防蜡和降粘,其目的在于提高原油的采收率。磁处理后为什么会改变水的注射特性和防蜡,降粘仍然是一个悬而未决的问题我们对上述增注问题进行了实验研究。戊烷、己烷、庚烷是原油的标型化合物,实验室常以这些化合物进行驱油的 Permanent magnet technology has been widely used in medical, industrial and agricultural fields. In recent years, the magnetization technology has been widely used in the petroleum industry. Most of the applications focus on water injection, wax prevention and viscosity reduction, with the aim of improving the recovery rate of crude oil. Why changing water injection characteristics and wax prevention, viscosity reduction remains a pending issue after magnetic treatment We conducted an experimental study of the above injection problem. Pentane, hexane, heptane are the standard compounds of crude oil, the laboratory often with these compounds for oil
