摘　　要：常规有机地球化学方法评价生油岩存在不足。本文分析测井资料评价生油岩的研究现状 ,研究了苏北盆地下第三系生油岩的测井响应特征 ,利用测井资料连续性的优势 ,应用ΔlogR技术建立起声波时差曲线和电阻率曲线与有机质含量间的定量关系 ,进而计算出烃源岩段的有机质含量的连续分布值 ,有效的弥补实验室测样的不足 ,为生油岩评价及油气资源评价提供更加合理的生油岩厚度和有机质丰度参数。Deviations exist in the chemical methods for studying source rock. This paper pays attention to analysis of the today's condition of well-logging information application on source rock evaluation, and studies the well logging responds of lower Tertiary source in Subei basin. According to ΔLogR technique, sonic transit-time and resistivity curves can be used to determine accurately the organic richness and provide a continuous TOC value. These work correct validly deviations of laboratory sample analysis, and provide reasonably the thickness of source rock and organic carbon contest for evaluation of source rock or petroleum resource.
