摘要
动液面滤波是油井检测动液面的关键技术之一。文章利用谱减法处理油井动液面信号,消除背景噪声的影响,并改进谱减法应用到动液面滤波,取得较好的滤波效果,从而提高对液面反射波位置的辨识能力。
Dynamic level filtering is one of the key technologies in dynamic level detection for oil-well. Dynamic level signals are processed with spectral subtraction for eliminating the background noises in this paper. The improved spectral subtraction is used for dynamic level filtering, which has better filtering effect, so that dynamic level identification is improved.
