【摘要】 在注水开发油藏中,当油藏达到高含水期时,确定剩余可采储量是油藏经营管理决策的重要依据。本文针对法21断块10多年生产过程中暴露出的开采矛盾,在分析其地质特征和开发特点的基础上,建立了该断块的地质模型,应用CMC油藏数值模拟软件的IMEX模拟器对该断块进行水驱历史拟合,从定性认识到定量分析,对各小层剩余油分布状况进行准确描述,对剩余油的影响因素进行了分析,对该断块开发调整提出了指导性建议。更多还原

【Abstract】 In water flooding reservoirs. after entering high water cut period, residual recoverable reserves is the important basis ol reservoir management. In accordance with critical problems revealed during more than 10 years of production in Fa 21 fault block, geological model has been established for this block based on analysis of geological characteristics and development features. Water flooding history match has been conducted for this block by using IMEX simulator of CMC reservoir numerical modeling software. Residual oil distribution in each sub-zone is described qualitatively and quantitatively, influence factor of residual oil is analyzed, and suggestions are given to adjust development in this block.更多还原
