1987年以前,从苏联报导的一些文献中看到,为了降低油气水集输系统的水阻,除了以往的化学法和热力法以外,又提出了物理场的作用,即磁场。有经验证实:永久磁铁和油气水混合流相互作用时,可使管输能力提高9～23%,这不仅对含水98～99%的高含水原油,而且对无水原油也如此。同时磁场还可降低原油乳化液的稳定性,削弱了原油的结蜡强度。但国立东方石油设计院的对此表示怀疑,他通过实验室试验得出了不同的结论:1、从试验结果看,加与未加磁场重质原油的粘度差别不大,说明磁处理未能
Before 1987, from some articles reported in the Soviet Union, it was observed that in order to reduce the water resistance of the oil-gas water gathering and transport system, in addition to the conventional chemical and thermal methods, the role of the physical field, that is, the magnetic field, was proposed. Experience has shown that when the permanent magnet interacts with the mixed flow of oil, gas and water, the capacity of the pipe can be increased by 9-23%, which is not only for high-water-content crude oil containing 98-99% water, but also for dry crude oil. At the same time the magnetic field can also reduce the stability of the crude oil emulsion, weakening the wax waxing strength of crude oil. However, the National Dongfang Petroleum Design Institute expressed doubts about this. He came to different conclusions through laboratory tests: 1. From the experimental results, there is not much difference in viscosity between the crude oil added and the non-added magnetic field, indicating that the magnetic treatment failed
