摘　　要：介绍了生油岩的测井响应特征以及生油岩定性和定量评价方法。利用测井资料评价生油岩的依据是生油岩在不同测井曲线上的响应特征。采用自然伽马能谱测井定性识别生油岩,利用声波法和电阻率法定量计算生油岩参数,根据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多种方法,对王46井孔店组地层生油岩进行定性和定量评价,并结合岩心分析资料确定出王46井孔店组有机质的丰度、有机质成熟度和有机质类型等。最后依据岩心分析资料,对不同计算方法的计算结果进行误差对比分析,证明了利用测井资料对该井生油岩评价的可靠性。This paper describes the logging responses of oil source rock and its qualitative and quantitative evaluations. The different responses of oil source rock on different logging curves provide bases for evaluation of oil source rock We used natural gamma ray spectrometry log to qualitatively identify oil source rocks, calculated parameters for the oil source rocks on acoustic longs and resistivity logs, and quantitatively evaluate the oil source rocks with regression analysis of the content of organic carbon with uranium, thorium, and kalium. The method was demonstrated with the evaluation of the oil source oils of the Kongdian Formation in well Wang 46. With core data, we determined the abundance, maturity and types of organic materials, and examined the results from different methods.
