Abstract: This paper presents in?depth research of the fracture?controlled factors, reservoir types and fracture systems of the epimetamorphic rock buried hill reservoir of Budate group in Sudeerte Oilfield in Hailar basin. The results show that the formation of the buried hill reservoir fractures is related to the tectonic movements here, with multistage shaping and filling features. The reservoir types mainly include the pore?fracturevug type and the pore?fracture type. The fault activity differences lead to different development of fractures in different fault blocks: near the intense faults, the reservoir rock developes best, with good petrophysical properties; while away from the faults,the reservoir rock less developes, and the petrophysical property is poor. For the fault blocks with poor developing fractures in the buried hill reservoirs, there exist top and inside fracture network systems in the vertical, which have big differences in reservoir type, petrophysical property and oil productivity, etc
