| Modeling, program, and modeling validation of detecting of wave-arriving of well-logging are comprehensively researched by adopting much information of data character of logging, signal processing, data explaining, programming and a thoroughly great lot of the scientific studies, lab analysis literature etc. According to abundance of well-logging data, this text designs a type of method for wave-arriving-time detecting of primary wave and secondary wave of sound wave logging signal, Slippage Windows method, which carries out by visual C++ language, based on MFC. This method, by time-analyzing of logging data, designs computing means for primary wave and secondary wave respectively, with amplitude difference of P and S waves theory, and characteristics of signal noises and Stationary. The wave-arriving curves are protracted by the program, whose data resource comes from the data of well of Xu-2nd section of Chuan-luo 652, and they are both checked up by two current methods: AC Curve and Dot Plotting. The integrative chart is protracted and displayed with the tools of Slippage Windows and current ones. |
