为了更有效地利用测井资料识别岩性，以中国大陆科学钻探工程主孔超高压变质岩的测井与岩心化学分析资料为对象，研究两者之间的内在关系。从相关文献中搜集和整理了主孔的189个岩心样品的全元素分析资料，提取了岩心分析与测井响应的样本数据。在此基础上，分析了氧化物含量与常规测井响应的统计关系，并通过逐步线性回归方法，建立了氧化物含量的测井评价模型。利用测井资料，计算主孔72～2010 m 井段地层的氧化物含量，对主孔地层岩性和钛矿（化）发育特征进行解释。研究表明，对于复杂的变质岩类，常规测井响应与地层元素组分之间存在内在的联系；在获得岩心全元素分析数据的条件下，利用测井资料建立地层化学组分的评价模型，能够为岩性与含矿分析提供更为直接的数据。

Well logging is facing more and more questions about complicated lithology interpretation.In or-der to identify lithology effectively by taking well logging,logging and core test data of main holes in super high pressure metamorphic rocks from Chinese Continental Scientific Drilling Project(CCSD)as examples, internal relations between conventional logging data and element component of stratum have been studied. Whole elements analysis information of 189 pieces of core samples have been collected,and the sample data of core analysis and corresponding logging datas have been extracted.On these basis,statistical relation-ship between oxide contents and normal corresponding logging datas has been analyzed.By using stepwise linear regression method,logging evaluation model of oxide content has been established.The oxide con-tents of main holes in 72 ~2010m section have been calculated by using logging data,and lithology and mineral development characteristics of main holes have been explained.It is showed that immanent connec-tion exists between conventional logging response and element component for the complex metamorphic rock.On the condition of gaining element analysis data,by using well logging data,evaluation models of chemical components in strata has been set up.It can provide more direct data for lithology and ore analy-sis.
