Abstract

Abstract: The deep-water zone in the Baiyun Sag,Pearl River Mouth Basin,is an important prospect area for oil and gas exploration in the northern South China Sea,but the understanding of the system tracts' composition and the depositional evolution process of the deep-water fans is still to be strengthened. Based on the comprehensive analysis of 3-D seismic profile,well logging and drilling data and plane properties,we discussed the evidences to identify FSST and LST,described and compared the sedimentary facies distribution characteristics and spatio-temporal evolution processes of the deep-water fans in the two system tracts. The result suggests that the fan in FSST is a small tongue-shaped fan,supplied by single sandy source vertically,whereas the fan in LST is a large irregular superposed fan with multi-line sources of mixed sand and mud,getting rid of major provenance supply from the delta. During the transformation from the former to the latter with multi-factors coupling,we speculate that such synthetic factors as sufficient sediment supply at the continental shelf break and relative sea level changes,function to provide a fundamental background;simultaneously,the strong coastal currents from southwest to northeast can be a favorable factor for the transformation.

Key words: deep-water fan, turbidity sediment, system tract, sequence stratigraphy, Baiyun Sag, Pearl River Mouth Basin
