摘　　要：在现今的勘探开发中,许多测井识别气层的主要资料只有普通电法测井、声波测井及中子伽马测井,为了利用各项测井资料有效识别天然气,我们提取了声波时差相对比值、中子伽马归一化值及电阻率相对比值等特征参数。并在此基础上,应用交会技术和数理统计方法建立了有效地快速直观显示天然气层的标准和方法,为统计学应用于测井资料识别天然气层提供了科学依据。now, in the exploration and development, the most of logging identify to the natural gas are based on only general electrical logging, acoustic logging and neutron--gamma logging, in order to use the various logging information to identify the natural gas, we extracted such as acoustic relative ratio, neutron-gamma normalized value and the resistivity relative ratio parameters. And on this basis, utilize cross --plot and mathematical statistical methods to quickly set up an effective visual display of natural gas layer standards and methods, provided a scientific reference for identify the natural gas based on statistics.
