结果表明：该区下白垩统主要发育冲积扇、扇三角洲、水下扇、三角洲、河道、湖泊等多种沉积体系及火山岩体。

High stand system tract is composed of coast and shallow lake sedimentary system, fan delta sedimentary system and turbidite fan sedimentary system.

高水位体系域主要由滨浅湖沉积体系、扇三角洲沉积体系和浊积扇沉积体系组成。

Character of fan delta sand body is confined by sediments resource, sedimentary landform, and sedimentary environment, etc.

扇三角洲砂体的沉积特征与碎屑供应、古地貌和沉积环境密切相关。

Physical properties of the sandy conglomerate reservoirs differ greatly in different depositional environments, and the best occurs in underwater distributary channel on fan delta front.

砂砾岩储层的物性随着沉积环境的不同表现出较大的差异，且以扇三角洲前缘亚相水下分流河道微相最好。

The distribution of concealed oil accumulation is controlled by the fore part of delta, nearshore fan and turbidite fan in Gaoyou sag.
