【Abstract】 This paper deals with the interference of logging signals encountered in the construction of cement bonded acoustic logging in eight sectors. The hardware design of the acoustic logging synchronous pulse signal front-end modulating in the acoustic logging module of PXI bus of surmounting ground system was discussed. At the same time, several methods for correctly recognizing synchronous signal of sector acoustic logging were introduced. In the end, a kind of eight-sector acoustic logging synchronization signal de-spurious technology was brought up. The problem of misidentification of synchronization head of logging signal has been successfully solved.更多还原
