摘要
依据状态空间模型与时间序列模型的基本关系,考虑抽油机井热洗清蜡实际,本文提出了一种新的自适应滤波器,应用这种滤波器确定的热洗周期具有很高的精度,对生产具有重要意义。
According to the heat-wash practice of oil wells and on the basis of main relation of state space models and time series models, a new adaptive filtering estimator which can be applied to heat washing process is given in the paper. The estimator has great practical significance for determining heat-wash periods of wells in actual production.
