The Study of Formation Elements Logging Interpretation Method

In order to apply pulse neutron formation elements logging tool, the research on the interpretation method of the formation elements logging was performed. A standard spectrum library of the formation elements was obtained, and an interpretation software was compiled, through which，the element yield, dry weight (mass percent content without crystalline water) and mineralogical-composition could be obtained. Comparing the interpretation results with the data from the cored well showed that the interpretation results had a good consistency with the core test results，which provided data bases for the evaluation of complex lithology and accurate calculation of porosity.
