Accumulation Process of Ultra-low Permeability Reservoirs in Yanchang Formation Ordos Basin: A case from Gufengzhuang-Mahuangshan area
摘要
Abstract
Oil reservoirs in Chang 6 and Chang 8 members of Yanchang Formation in Gufengzhuang-Mahuangshan area of Ordos Basin are typical ultra-low permeability reservoirs.Comprehensive analysis of homogenous temperatures of fluid inclusions and geothermal and burial history shows that oil accumulation of Chang 6 and Chang 8 members happened in early Cretaceous.During the oil accumulation petroleum generating from Chang 7 source rock only charged into Chang 8 reservoir at the early stage,then charged up and down into Chang 6 and Chang 8 at the middle stage,and only filled into Chang 6 reservoir at the late stage.The difference of accumulation process was controlled by the relationship between source and reservoir,and the peak time of hydrocarbon generation,and the reservoir tightness prior to the accumulation.关键词
