摘　　要：岩石热解录井参数直接反映岩石中烃类组分的含量,是评价储层含油性的一项重要技术手段。由于分析样品的类别不同,导致分析结果有着比较大的差异,严重影响到基于岩心样品分析结果建立的解释图板的应用效果。通过多元线性回归分析建立岩屑热解录井参数校正方法和模型,将岩屑分析结果回归到岩心分析的“标准尺度”,极大地提高了解释图板的解释精度,为储层评价提供了更准确的参考依据。Rock pyrolysis logging parameters directly reflect the content of hydrocarbon components in rock and are an important technical means to evaluate the oil bearing properties of reservoir.Due to the different categories of the analyzed samples,the analysis results are quite different,which seriously affects the application effect of the interpretation chart based on the analysis results of core samples.The cuttings pyrolysis logging parameter correction method and model are established through multiple linear regression analysis,and the cuttings analysis results are regressed to the"standard scale"of core analysis,which greatly improves the interpretation accuracy of interpretation chart and provides a more accurate reference for reservoir evaluation.
