【摘要】:由于外來稠油的混入,使得江漢油田鐘市聯(lián)合站原油破乳效果變差?疾炝40~70℃條件下,13種市售破乳劑與現(xiàn)場破乳劑FT-1032的破乳效果,并用界面張力儀和凝膠滲透色譜儀對破乳劑進行了表征及作用機理分析。實驗結(jié)果表明在評價溫度范圍內(nèi)破乳劑YT-31、JL-65、TK-21的效果較好,且優(yōu)于現(xiàn)場使用的破乳劑。為了獲得更好的破乳效果,將以上三種破乳劑兩兩復(fù)配篩選,得到了TK-21/JL-65(質(zhì)量比)=4∶1的復(fù)合破乳劑最優(yōu)配方。針對現(xiàn)場溫度波動情況,對不同溫度下破乳劑的加劑量進行了優(yōu)化,優(yōu)化后的破乳劑質(zhì)量濃度為C_(40℃)=50mg/L,C_(50℃)=40mg/L,C_(60℃)=25mg/L,C_(70℃)=20mg/L,F(xiàn)場試驗結(jié)果表明,10d的原油含水率都小于0.5%,破乳效果較好。
