Research on Displacement Calculation of Dynamometer Card Based on Kalman Filter and Discrete Numerical Integration

摘要：

　　In order to calculate the dynamometer card of oil well using acceleration sensor,the algorithm which combined by Kalman filter and discrete numerical integration is proposed.It can be applied to calculate the displacement and precipitation displacement period of oil well dynamometer card.The Kalman filter not only filters out the noise of the acceleration signal,but also maintains the original shape feature.The accurate precipitation of the displacement period ensures the correctness of displacement.The discrete numerical integration algorithm can make the relative error of displacement measurement less than 1%,which meets the requirement for dynamometer card accuracy.It is suitable for different types of oil wells.
