摘要：Development of Shahejie Formation lithologic reservoirs and deep buried hill hydrocarbon reservoirs in the western slope of Shulu Depression. After years of exploration and development practice, the types of buried hill hydrocarbon reservoirs oil and gas reservoirs are diverse, and the hydrocarbon accumulation conditions are not clear, which restricts the pace of oil and gas exploration. Therefore, this paper studies the types and distribution laws of buried hills and the reservoir forming conditions of buried hill hydrocarbon reservoirs. The results show that the west slope of Shulu Depression can be divided into five types: erosion buried hill, fold-erosion buried hill, fault block-erosion buried hill, fold buried hill and fault block buried hill. The buried hill trap is mainly controlled by three factors: unconformity interface, geologic fault and stratigraphic overlap occlusion.
