Title: Fan Delta Depositional Modes in Shuanghe Oilfield
Abstract: It was considered by predecessor study that Eh 3 in Shuanghe Oilfield was a Gilbert type fan delta. Study of its depositional background, sedimentary facies distribution, its deposit properties, sedimentary structure and its sedimentary sequence shows that in the studied area depositional slope is gentle, frontal subfacies is developed, deposit particles are relatively fine in the target zone, its sedimentary structure is mainly of drag flow sedimentary structure, gravity flow sedimentary structure is undeveloped. The characteristics of its sedimentary sequence is not a typical fluvial depositional one, or a obvious gravity flow depositional one, there are bigger differences among these 3 deltaic modes, the fan delta sedimentary mode is similar to that of continental fan delta formed under more gentle conditions on the basin bottom.
