摘　　要：对苏德尔特油田布达特群浅变质岩潜山油藏裂缝控制因素、潜山储集层储集类型及裂缝系统深入研究后认为,潜山储集层裂缝的形成主要与所经历的构造运动有关,具有多期形成、多期充填的特点,储集类型主要包括孔隙-缝洞型和孔隙-裂缝型两种。由于断层活动强度的差异,导致不同断块裂缝发育程度不同,活动强度大的断层附近储集层最为发育,储集层物性好,反之,储集层较不发育,物性也较差。潜山储集层裂缝发育较差的断块,纵向上存在顶部和内幕两个裂缝网络系统,两个裂缝网络系统在储集类型、储集层物性和产油能力方面存在较大差异。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 inelude the pore-fracture-rug 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.
