Abstract
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.关键词
