摘　　要：通过对平山湖地区11口井的测井资料进行分析,初步掌握了该区含煤岩层的地球物理特性及其在视电阻率、密度、自然伽马、声波时差、自然电位等测井曲线上的响应特征。总结出一套适合该地区的测井方法,如各种测井参数的数据计算方法与曲线处理技巧,为该类地区使用TYSC-3Q测井仪器进行测井提供了参考依据。针对该地区煤层具有中高阻、低密度、低放射性、高时差、弱自然电位的物性特征,以多个实例介绍了煤层在不同测井参数曲线上的识别方法及定量解释原则。After analyzed well logging data of 11 boreholes in the Pingshanhu area, has preliminarily gripped coal-bearing strata geophysical characteristics and their responding features on apparent resistivity, density, natural gamma, sonic differential time, spontaneous potential traces in the area. A set of well logging method has been summarized adaptable to this area, such as calculation on data of various logging parameters and traces processing techniques thus provide reference frame for using the TYSC-3Q logger in the area. In allusion to physical properties of medium to high resistance, low density, low radioactivity, high differential time, weak spontaneous potential of coal seams in the area, using multiple living examples introduce coal seam recognition methods and quantitative interpretation principles on different well logging parameters traces.
