摘　　要：应用测井曲线中煤层、岩层在视电阻率、自然伽玛、伽玛一伽玛等物性参数曲线上显示的异常幅度、异常宽度、异常形态、异常组合特征、特殊异常5个方面的特征进行对比,研究测井曲线特征,确立煤系地层中的标志层,定位煤系地层中的主要煤层;利用测井曲线中的特殊异常(异常重复、测井特征缺失)判定断层及其位置;利用测井参数响应值综合研究、分析,对煤系放射性环境进行评价,发现其他有益矿产(如黄铁矿、煤铀矿)。测井结果与该区地质结果一致。The characteristics of amplitude, width, form, combination feature of abnormal segment and special abnormal segment displayed in apparent resistivity, natural gamma, gamma-gamma and other physical property parameters curves of coal seam and rock stratum in logging curve were contrasted to study the features of logging curve and determine the marker bed and main seam of measured coal strata, and the special abnormal segments of logging curve such as abnormal repetition, logging fea- ture deficiency were used to predicate fault and its location, then response values of logging parameters were comprehensively studied and analyzed to evaluate radiation environment in measured coal strata and discover other useful mineral resources, such as pyrite and uranium ore. The logging result was in accordance with geological result in this area.
