电磁场式油水界面测量分析及数据优化方法

Oil-Water Interface Analysis and Data Optimization Methods of Electromagnetic Field-typed Measuring Device

应用电磁场式油水界面测量装置进行测量时,由于测量受到实际主观和客观条件的制约,测量数据往往出现若干坏点。笔者对坏点进行认真分析,通过软件优化的方法可以对数据进行修正,并提出了最值过滤法、定点修正法和区域去噪法3种数据优化方法,这3种优化方法在不同的情况下都能得到很好的应用,且后一种方法较前一种都有很大的提高。

Both subjective and objective condition can influence measurement data much while applying electromagnetic field-typed measuring device to oil-water interface detection.Basing on analyzing bad data that can be amended with software optimization method,three kinds of data optimization methods like maximum/minimum value filtering method,fixed-point correcting method and regional denoising method were proposed and applied well in different conditions,but the latter method outperforms the former one.
