摘要
注水井进行深部调剖(驱)是油田开发后期严重非均质性油藏高含水阶段稳油控水、提高注水波及系数的重要技术手段。从深部调剖的化学剂、物理模拟实验、决策技术、配套工艺技术等方面系统分析了国内外深部调剖(驱)技术的研究和应用现状以及存在的问题。根据高含水油田开发现状及需求,提出了深部液流转向改善水驱开发效果的技术发展趋势,即立足高含水油藏开发后期实际需要,在精细油藏描述及油藏数值模拟研究的基础上,以开发廉价长效的深部调剖(驱)剂为核心,深入开展机理理论研究,完善准确、快捷的决策技术及相关配套工艺技术,形成深部调剖(驱)技术的工业化规模,实现深部液流转向改善高含水期非均质油藏水驱效率的目的。
In-depth profile control is an important technique for stabilizing oil production, controlling water production, and improving waterflood sweep efficiency in severely heterogeneous reservoir at high water cut stage in the late life of oilfield development. The current situation and problems in the study and application of in-depth profile control at home and abroad have been analyzed in respects of chemicals, physical simulation, decision making, and matching techniques. For high water cut oilfields, it is proposed to improve waterflooding effect by deep fluid diversion. The research of in-depth profile control technology shall put emphasis on the development of low cost and enduring profile control agent on the basis of fine reservoir description and numerical simulation so as to improve decision making and matching techniques, make in-depth profile control a conventional technology, realize deep fluid diversion, and improve waterflood efficiency for heterogeneous reservoirs at high water cut stage.
