Abstract:

Natural fractures developed well in sandstone reservoirs of Upper Triassic Yanchang Formation in Jiyuan area, Ordos Basin. The fractures are high angle tectoclase generated in the slight tectonized areas. These fractures are generallyNW-SE striking, though some are NE-SWstriking. Lowpermeability sandstone reservoirs and the Yanshanian Movement are the key elements for the formation of these fractures. Because of the existence of the tectoclase, a uniquely petroleum migration and accumulation model is formed in this area: petroleum migrates to upper reservoirs through fracture multipoint; meanwhile, the distribution of oil reservoir is multi-area in horizon, and many oil reservoirs in vertical in the same areas.

Key words: Chang 62 reservoir, sedimentarymicrofacies, reservoir physical property, oiliness, Ordos Basin
