基于电磁技术优选最佳油田管道除垢参数

Optimization of oil field pipe descaling parameters based on electromagnetic technology

截至2016年底,我国原油管道约2.62万km,原油管道运输较其他运输方式有"安全、环保、低耗、节能、提高社会经济效益"的优势^([1-3]),管道长期运输有蜡晶析出,蜡晶析出后会变成污垢附着在管道内壁,使管道变细、流动阻力增加、压力降低。电磁防垢技术作为一种物理除垢处理技术,越来越受到人们的推广和应用。因此,优选电磁防垢的参数输油管线经济有效地进行防垢具有深远的意义。为了优选电磁技术油田管道除垢效果的最佳参数,设计了一套模拟电磁波对输油管道的除垢装置,模拟不同线圈匝数以及不同频段下电磁波除垢效果实验。通过对实验结果分析,得出线圈匝数在25圈、电磁波频段在14~16k Hz范围内,除垢效果达到最佳。

As of the end of 2016, China＇s crude oil pipeline about 26,200km, crude oil pipeline transport than other modes of transport ＂safety, environmental protection, low consumption, energy saving, improve social and economic benefits＂ advantaget long-term pipeline has wax Precipitation, wax precipitation will become a dirt at tached to the pipe wall, so that the pipeline thinner, increased flow resistance, pressure reduction. Electromagnetic anti-scaling technology as a physical cleaning technology, more and more people to promote and use. It is prefer- able that the parameters of the electromagnetic scale prevention oil pipelines are economically efficient and have a far-reaching significance. In order to optimize the best parameters of the pipeline cleaning effect of the electromagnetic field, a set of anti - scaling device for the electromagnetic wave to the oil pipeline was designed to simulate the number of turns of different coils and the effect of electromagnetic wave descaling in different frequency bands. Through the analysis of the experimental results, the coil turns in the 25 laps, electromagnetic band in the range of 14-16kHz, the cleaning effect to achieve the best.
