在阿拉斯加进行了4个单井化学示踪试验(SWCTT),结果显示,注低矿化度水大幅度降低了水驱残余油饱和度(Sorw)。低矿化度水驱(LoSal)EOR方法的采收率为OOIP的6%～12%,使水驱采收率提高了8%～19%。目前正在对阿拉斯加北坡油藏的低矿化度水驱采油进行积极的评价。
Four Single Well Chemical Tracing Tests (SWCTTs) were conducted in Alaska and the results show that injection of low salinity water drastically reduces the water flooding residual oil saturation (Sorw). The recovery of low salinity waterflooding (LoSal) EOR is 6% ~ 12% of that of OOIP, which increases the waterflood recovery by 8% ~ 19%. A positive assessment is currently underway of low salinity waterflood oil production in the north slope of Alaska.
