根据今年八月在昆明召开的西南三省煤田测井经验交流会上所介绍和交流的内容,对当国内外煤田测井概况和发展动态,作如下的综合报道。测井方法除目前常用的视电阻率、自然电位、自然伽玛、散射伽玛四种测井方法外,国内外已广泛开展声波、三侧向及中子——中子测井。其中声波测井不但可测量声波时差,还可以测量声幅,甚至测量全波列声波,从而可能获得纵波、横波、端利波、管波等传播速度和幅度衰减讯息;声波测井还用双发回收进行的补偿声波测量,有的公司利用计算机处理技术把单发双收
According to the introduction and exchange at the well logging experience exchange conference in the three provinces of southwestern China held in Kunming in August this year, the following summarizes the current situation and developments of coalfield well logging at home and abroad. Well Logging In addition to the commonly used four methods of apparent resistivity, natural potential, gamma ray and scattered gamma, well-known acoustic wave, three-lateral and neutron-neutron logging have been widely carried out at home and abroad. The acoustic logging can not only measure the acoustic time difference, but also measure the amplitude of the sound, and even measure the full-wave sound waves so that the propagation speed and amplitude attenuation information of the longitudinal wave, the transverse wave, the terminal wave and the tube wave may be obtained. Send compensation for the recovery of sonic measurement, and some companies use computer processing technology to single double
