摘要
低渗透油藏渗流阻力大,注水启动压力高,常规注水驱油效果差。超高压注水能有效克服渗流阻力,增大注水量,提高驱油效果。超高压注水采用的撬装式注水站,具有投资小、施工周期短、工艺简单、可移动易地重复使用的特点。
Large percolation resistance,high waterflooding starting pressure and bad effect of conventional waterflooding are common in low-permeability reservoir.Adopting ultrahigh-pressure waterflooding can conquer percolation resistance,increase water injection rate and improve oil displacement.Skid-mounted ultrahigh-pressure waterflodding station has the characteristics of small spending,short period of construction,simple technology and reuse.
