Great progress has been made in the research of source rock by well logging.Source rock evaluation has been developed from qualitative identification to quantitative calculation,which can resolve the difficulty of source rock evaluation lack of core data in area division.Organic material and clay mineral are important elements which affect well logging response.The disparity of petrophysical and electro-cheimical property which caused for the difference of organic matter and clay mineral′s type,abundance,compaction,occurrence state etc,is the basis of source rock identified and evaluated by using logging information.Under the present exploratory situation,the research on source rock by use of logging data will develop to further degree.The mechanisms of correspondence relation between geochemistry behavior and log response,the method developed by use of electro-chemical feature,petrophysical lab and numerical analogue,are new trends of research on evaluating source rock with logging.
