摘要

Suderte Oilfield in Hailar Basin is a high-production and highly oil-enriched structural belt. Its main oil layer-Xing’anling Group can be divided into four lithological intervals (oil layer group ). The oil layer is analyzed from the viewpoints of the sandstone lithology, diagenesis the characteristics of pore structures and so on. The studies show that the tuffaceous debris is widely distributed in above four oil layer groups, belonging to pyroelastie deposit ; the main diageneses are compaction, cementation and recrystallization, the else are metasomatism and alteration; the pore type is mainly primary intergranular pore; there is tuffaceous debris in four oil layer groups, among them the porosity and permeability in Group are the best, the next is Group Ⅲ, the worst is Group Ⅱ and Ⅳ.
