抽油井下设备磁化原因分析及解决方法

抽油井井下设备磁化现象几十年来一直没有引起人们的高度重视 ,直到目前仍有不少人不了解井下磁化现象及其给油井造成的危害 ,还有一些人对油井是否存在着磁化现象持怀疑态度。大量的现场检测证明 ,抽油井磁化现象是一个客观存在的事实。抽油井被磁化后 ,不仅能够导致泵漏 ,泵效低 ,严重影响油井的正常生产 ,而且造成检泵频繁 ,使作业费居高不下。针对磁化现象给油井造成危害以及抽油井被磁化的机理进行了初步的分析研究 ,并得出了一些结论。对如何解决抽油井被磁化的问题提出了看法和建议。

CAUSE ANALYSIS AND SOLUTION OF MAGNETIZATION ON DOWNHOLE EQUIPMENT IN OIL PUMPING WELL

For dozens of years magnetization phenomenon wasn't attached great emphasis from the beginning of the year up to now and so far many persons are unknown in magnetization phenomenon, which brings a boat harm to oil wells, other persons even hold it a skeptical attitude to whether magnetize or not, a large number of on-site detect have proved that magnetization phenomenon in oil pumping well has became an objective existence. After oil pumping wells are magnetized, not only results in pump leaking, low pump efficiency, seriously effects on sound production but also gives rise to frequently overhauling pump, and operative cost raising. We have carried out preliminary analysis and research on both harm to oil well arisen from magnetization phenomenon and magnetization mechanism of oil pumping unit as well as gained some conclusions that have proposed out both views and suggestions how to solve magnetization problem in oil pumping well.
