河北省第二煤田地质勘探队最近试验成功磁带测井记录,即将各种测井参数直接录制在磁带上,一次成线。曲线的回放工作可在野外、也可在室内进行,回放时能任意选择合适的技术条件(如横向、纵向比例,时间常数等),从而提高了资料的记录质量和使用价值。在现场测井时,用磁带记录,只须对各种参数录制一次,而且不存在操作其它仪器 The second Coalfield Geological Exploration Team in Hebei Province recently successfully tested the tape logging record, that is, various logging parameters are recorded directly on the tape, once into a line. Curve playback in the field can also be carried out indoors, playback can be arbitrarily select the appropriate technical conditions (such as horizontal, vertical ratio, time constant, etc.), thereby enhancing the quality of records and use of value. Logging in the field, the tape recording, only a variety of parameters recorded once, and there is no operation of other instruments
