Adopting the velocity varying mapping technique in the light of the character of severe varying velocity in that region,the structural attitude of Benbutu anticline has been clearly clarified and geologic reserve has been further ascertained.The structural interpretation and reservoir prediction technique is mainly used in a process of discovery and exploration of eastern Benbutu oil bearing block.The key factor of having excellent results in a process of oil gas exploration in Yanqi basin is to adopt correspondent geophysical prospecting technique in a different exploration stage and aimed at different exploration objects.
