摘要
Based on the review of deepwater depositional elements’ research in the world, combined with the exploration practice of Baiyun deepwater area, the deepwater depositional elements in Baiyun deepwater area are studied. The deepwater depositional elements include channel, levee-overbank, sheet sand and mass-transport deposit. The channel is one of the main components of deepwater deposits and the important reservoir in Baiyun deepwater area. The channel fills have been classified into three broad categories: erosional, erosional/aggradational and aggradational channel genetically.
