摘　　要：烃源岩测井评价是页岩油“四品质”评价中一项重要的研究内容。目前,针对陇东长7_(3)页岩油应用测井资料来进行烃源岩识别与有机碳含量评价已较为广泛,但精度不高且其他有机地化参数测井定量评价相对空缺,烃源岩测井评价标准还未完善。因此,针对以上问题,本文首先阐述了鄂尔多斯盆地陇东地区烃源岩特征;然后,精细构建了研究区烃源岩测井评价参数体系,特别是针对有机碳含量计算提出了声电面积包络法、细分岩性法等多种算法,有效提高了计算精度;最后,基于烃源岩品质综合评价指数,建立了陇东长7_(3)烃源岩分类评价标准,为后续“甜点评价”提供技术支撑。Logging evaluation of source rocks is an important research content in shale oil'four quality'evaluation.At present,the application of logging data to source rock identification and organic carbon content evaluation of Longdong Chang7_(3)shale oil has been widely used,but the accuracy is not high and other organic geochemical parameters are relatively vacant.The logging evaluation standard of source rock is not perfect.Therefore,in view of the above problems,this paper first expounds the characteristics of source rocks in Longdong area of Ordos Basin.Then,the well logging evaluation parameter system of source rock in the study area is constructed in detail.In particular,a variety of algorithms such as acoustic-electric area envelope method and subdivision lithology method are proposed for the calculation of organic carbon content,which effectively improves the calculation accuracy.Finally,based on the comprehensive evaluation index of hydrocarbon source rock quality,the classification and evaluation criteria of Chang 7_(3)hydrocarbon source rock in Longdong were established,which provided technical support for the subsequent dessert evaluation.
