Cause Analysis on Abnormal Pulse Signals of BH-VDT Vertical Drilling Tool

  • 摘要: 为分析BH-VDT垂直钻井工具钻进复杂地层时发送异常脉冲信号的原因,给消除异常脉冲信号提供依据,室内模拟了正常脉冲信号的波形、瞬时断路和欠功率造成的异常脉冲信号的波形,并分析了其波形特征。模拟试验结果为:瞬时断路造成的异常脉冲信号的波形具有随机性和多样性,断点出现在未发射脉冲波段时对波形幅值无影响;欠功率造成的异常脉冲信号的波形具有周期性和持续性,断点出现在脉冲发射期间时,波形幅值明显偏小。将现场采集的异常脉冲信号的波形特征与室内模拟异常脉冲信号波形特征进行对比,即可判断产生异常脉冲信号的原因。应用结果表明,分析现场采集的异常脉冲信号的波形特征,并将其与模拟异常脉冲波形特征进行对比,能准确判断出现异常脉冲信号的原因,为消除异常脉冲信号提供依据。
    Abstract: In order to analyze the causes of the abnormal pulse signals sent by the BH-VDT vertical drilling tool when drilling in complicated formations,and to provide the basis for eliminating abnormal pulse signals,by means of laboratory simulation test,the waveforms of normal pulse signals and abnormal pulse signals caused by instantaneous disconnection and underpower were simulated;and the characteristics of such waveforms were analyzed.The results were as follows:the waveforms of abnormal pulse signals caused by instantaneous disconnection showed the characteristics of randomness and diversity,and when the breakpoint appeared in the non-emitted pulse waveband,the amplitude of the waveform was not influenced.The waveforms of abnormal pulse signals caused by underpower showed the characteristics of periodicity and sustainability,and when the breakpoint appeared during the pulse emission,the waveform amplitude was significantly reduced.The causes of abnormal pulse signals could be determined by comparing the characteristics of the waveforms of field acquired abnormal pulse signals with that of the laboratory simulated ones.The applications showed that the causes of abnormal pulse signals could be accurately determined through analyzing the characteristics of the waveforms of field-acquired abnormal pulse signals and comparing them with those of the simulated ones,thus providing a basis for eliminating abnormal pulse signals.
