Dynamic Processing of the Right Border of Real Time Logging Signal in Wavelet Analysis
Zhu Xiao-dong · Journal of Zhengzhou University · 2010
Real time dynamic information is the information sources of accidents prediction of petroleum drilling.In order to locate the current dynamic signals in the optimum filtering deferent segments of wavelet dynamic filters,based on the combination of prediction and fitting,a right border dynamic processing method is put up in wavelet analysis of real time logging signals.The combination of prediction and fitting transfers the spot originally located at the right border of the dynamic signal to the middle part of the wavelet analysis.And then it exerts the accurate composition's advantage of wavelet processing.The application of this processing testifies the effectiveness of this combination.
