摘　　要：介绍了生油岩的测井响应特征、有机质特点及生油岩定性、定量评价方法。依据生油岩在不同测井曲线上的响应特征,利用电阻率、声波时差、自然伽马能谱等测井信息,采用自然伽马能谱测井定性识别生油岩、声波-电阻率法定量计算生油岩参数、利用岩心分析的有机碳含量与铀、钍、钾的关系回归计算评价生油岩等不同的方法,以滋2井、林30井、莱64井生油岩的定性、定量测井评价为例,分析测井资料在生油岩评价中的应用,在对不同的计算方法的结果进行误差对比分析后,认为测井资料在生油岩评价方面的应用效果明显。Introduced are log responses, organic matter features of oil source rock and its qualitative and quantitative evaluation methods. The rock has different responses on different log curves, e. g., its GR strength enhances, density reduces, resistivity increases and U-content increases, etc. Thus, with analysis of regression, it is easy to obtain the rocks.GR value, Rt and AC value to calculate G1 and （S1 ＋S2 ）, error from which is also analysed.
