摘要
通过对一例工作中实际发生的,罕见的直达波干扰声波时差测井泥岩地层测井曲线的案例分析,从声波测井原理和仪器的设计原理出发,结合测得的声波波形、测井曲线分析了故障产生的原因。找到了检查声波仪器直达波干扰的方法,以及解决方法。
The paper analyses a rare case of direct wave interfering in sonic slowness logging in shale formations occurred in logging operation.Based on the principles of sonic logging and the tool design,and combining with the measured waveforms and logging curves,this paper investigates the causes of the interference and in the end presents the method for checking direct wave interference on the tool and the solutions to the interference.
