In the late stage of waterflooding, multi-round profile control is an important measure to stabilize oil production and control water cut.
在水驱油田开发中后期,多轮次调剖是一项重要的稳油控水措施。

The original elastic energy in low permeability reservoir is generally small, so all the oil fields early or late adopt waterflooding to keep the pressure of the low permeability reservoir.
我国低渗透油藏的天然弹性能量普遍较小,所以基本上都先后采取了注水保持压力的开发方式。

The water-flooded layer interpretation becomes one of the most difficult problems in the middle-late stage of waterflooding, whose interpretation coincidence rate is usually around 80%.
