The double critical DIVA technique detection was conducted for 5 geological intervals on 4 well blocks, indicating the uniqueness of the technique. The application effect is even better, especially under the conditions of small lateral changes in lithology. The accuracy of the technique mainly depends on the velocity spectrum picking-up accuracy, horizon interpretation accuracy and the background velocity picking-up accuracy.ml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
