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。
According to the main development characteristics of the ultra-high water cut period of the heterogeneous thick oil layer in Shuanghe Oilfield, this paper starts with revealing the intra-layer structure of thick oil reservoirs and the genetic types and distribution of residual oil. Through the detailed description of three-dimensional quantitative thick layers and fine numerical simulation All-round evaluation and understanding of the controlling factors of the remaining oil enrichment sites, types and their formation in the period of extra-high water cut in heterogeneous crude oil reservoirs.
