Abstract

This paper provides a accurate method for dividing drilling debris. Firstly, K, Th and U counting rates of different drilling debris samples were measured by low background gamma spectrometer, and the relationship between sample quality and counting rate was obtained. Secondly, mudstone and limestone can be classified by the lithologic identification method. Finally, the specific lithology of mudstone can be divided by the relation of K, Th and U counting rates. Experiments have shown the accuracy of lithological discrimination of drilling debris by this method is up to 80%.
