摘要： 塔河油田奥陶系油藏为岩溶缝洞型油藏,大型溶洞是其主要的储集空间。目前单井注水替油已取得突破,但占储量80%的多井单元注水开发尚处于实验阶段。结合数值模拟和注水实践总结,开展了多井单元注水增油的机理研究,并初步总结出了“低注高采、试注判断连通实时调整、单元整体温和注水、井组差异管理”的缝洞型油藏注水开发模式,在现场应用取得了一定成效。

Abstract: The Ordovician reservoir in Tahe oilfield is a karst fractured-vuggy oil reservoir dominated by large-sized vugs as its reservoir spaces. At present, breakthrough has been made by single well waterflooding process, but it is in experimental stage by multi-well unit waterflooding process for areas with 80% reserves. Based on the numerical simulation and waterflooding practices, the mechanism of the mult-well unit waterflooding process is studied, and an effective pattern in field application is preliminarily summarized in this paper, namely, low water injection and high oil production, injection test to judge connectivity and adjust in time, whole unit gentle water injection and well groups separation management

Key words: Tarim basin, Tahe oilfield, fractured-vuggy reservoir, waterflooding, pattern
