This article describes the application of B P technique to pertinent questions in uranium logging data interpretation. Adopting the improved B P algorithm to establish network structure and thoroughly investigating the process, and the method constructing learning sample has been improved. Good results have been achieved through applying the B P model to recognize lithologies and forecast porosity.
