摘　　要：针对双河油田非均质厚油层特高含水期的主要开发特征，从揭示厚油层层内结构、剩余油成因类型及分布规律入手，通过厚层层内三维定量化精细描述、精细数值模拟和全方位评价，认识非均质原油层特高含水期剩余油富集部位、类型及形成的控制因素。In view of the development characteristics of inhomogeneous thick oil reservoirs at ultra -high water-cut stage in Shuanghe oilfield and starting withrevealing the intrastratal structure of thick oil reservoirs,this paper studics the genesis and distribution patterns of residual oil, residual oil enrichment position, types and control factors of its formation at ultra - high water -cutstage in inhomogeneous thick oil reservoirs through intraformational 3- D quantitativc fine description, finenumerical modeling and evaluation.
