随着煤田勘查中小口径绳索取芯钻探工艺的普及和深部资源勘探的展开,测井探管下井被卡的次数越来越多,测井事故率越来越大,测井探管的多参数组合显得越来越迫切。为此,本文阐述了煤田测井声波三側向探管的原理和主要故障处理方法,探讨了采用声波三側向探管测井的组合曲线,即三側向电阻率和声波时差两种测井参数五种方法曲线(即三側向电压、三側向电流、三側向电阻率、单收声波时差、双收声波时差)。对提高煤田钻探解释效果、测井效益具有一定的实际意义。 With the popularization of deep hole core drilling technology and exploration of deep resources in coalfield exploration, the number of well logging wells getting stuck is more and more, and the logging accident rate is increasing. The multi-parameters Combination is more and more urgent. Therefore, this paper describes the principles and main troubleshooting methods of the three-sided sounding probe in coalfield, and discusses the combination curves of three-sided acoustic logging with three-sided acoustic resistivity and acoustic time difference Well parameters of the five methods of curve (that is, three lateral voltage, three lateral current, three lateral resistivity, single-time sound wave time difference, double-time sound wave time difference). It has some practical significance to improve drilling interpretation effect and logging benefit of coalfield.
