摘要

针对八扇区水泥胶结声波测井施工过程中遇到的测井信号干扰问题,论述了超越地面系统PXI总线声波测井模块中声波测井同步脉冲信号前端调理硬件设计以及如何正确识别扇区声波测井同步信号的几种方法,并结合实际应用总结出一种八扇区声波测井同步信号去伪技术,成功地解决了测井信号同步头误识别问题。
        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.
