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。
低滲透油藏滲流阻力大,註水啟動壓力高,常規註水驅油效果差。超高壓註水能有效剋服滲流阻力,增大註水量,提高驅油效果。超高壓註水採用的撬裝式註水站,具有投資小、施工週期短、工藝簡單、可移動易地重複使用的特點。
저삼투유장삼류조력대,주수계동압력고,상규주수구유효과차。초고압주수능유효극복삼류조력,증대주수량,제고구유효과。초고압주수채용적효장식주수참,구유투자소、시공주기단、공예간단、가이동역지중복사용적특점。
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.
