截至9月7日，經過兩個月的運行，漠大線適應性改造工程完全達到設計要求，為中俄原油管道安全運行提供了可靠保障。
漠大線全長926.5公里。管道首站位于黑龍江省漠河縣，末站位于大慶市，自北向南途經黑龍江省和內蒙古自治區13個市、縣、區。漠大線一期設計年輸量為1500萬噸，是我國能源進口的重要通道。
漠大線2011年1月1日正式投入運行以來，由于原油物性與設計時采用的物性相差較大，一直滿負荷運行。冬季大興安嶺地區大雪高寒，車輛行駛緩慢，管道搶維修機械器具進場困難。加之高寒地區戶外作業時間短，漠河首站罐容儲備能力無法滿足突發情況下搶維修工作的需要，給漠大線安全運行帶來挑戰。
為解決漠(mo)(mo)河首(shou)站(zhan)高(gao)罐(guan)(guan)位運行(xing)風險(xian)，2012年(nian)5月(yue)(yue)(yue)10日，漠(mo)(mo)大(da)線適(shi)應(ying)性(xing)改(gai)(gai)(gai)造(zao)(zao)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)正式(shi)啟(qi)動(dong)。面對(dui)大(da)興安嶺地(di)區僅(jin)(jin)有(you)4個月(yue)(yue)(yue)施工(gong)(gong)(gong)(gong)(gong)作(zuo)業時(shi)間的(de)實際，工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)建(jian)設者(zhe)分秒(miao)必爭，倒排工(gong)(gong)(gong)(gong)(gong)期節(jie)點，清晰劃(hua)分施工(gong)(gong)(gong)(gong)(gong)作(zuo)業面，僅(jin)(jin)用40天(tian)完(wan)(wan)成(cheng)(cheng)5000多噸的(de)罐(guan)(guan)板運輸任務(wu)，45天(tian)完(wan)(wan)成(cheng)(cheng)14萬立方米(mi)土石(shi)挖(wa)填及儲罐(guan)(guan)基礎工(gong)(gong)(gong)(gong)(gong)作(zuo)，37天(tian)完(wan)(wan)成(cheng)(cheng)儲油(you)罐(guan)(guan)主(zhu)體安裝工(gong)(gong)(gong)(gong)(gong)作(zuo)。去年(nian)10月(yue)(yue)(yue)15日，漠(mo)(mo)大(da)線適(shi)應(ying)性(xing)改(gai)(gai)(gai)造(zao)(zao)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)4個儲油(you)罐(guan)(guan)完(wan)(wan)成(cheng)(cheng)上水沉降試驗(yan)，10月(yue)(yue)(yue)25日，漠(mo)(mo)河首(shou)站(zhan)新建(jian)罐(guan)(guan)區工(gong)(gong)(gong)(gong)(gong)藝管網最后一(yi)道焊口焊接完(wan)(wan)畢，標志(zhi)著漠(mo)(mo)河首(shou)站(zhan)新老(lao)罐(guan)(guan)區工(gong)(gong)(gong)(gong)(gong)藝管網具(ju)備連通條件。今年(nian)春季，經過(guo)建(jian)設者(zhe)緊鑼密(mi)鼓(gu)的(de)施工(gong)(gong)(gong)(gong)(gong)，漠(mo)(mo)大(da)線場區配套工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)相繼完(wan)(wan)成(cheng)(cheng)。7月(yue)(yue)(yue)9日，漠(mo)(mo)大(da)線適(shi)應(ying)性(xing)改(gai)(gai)(gai)造(zao)(zao)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)順利(li)竣工(gong)(gong)(gong)(gong)(gong)投(tou)產。 經過(guo)兩個月(yue)(yue)(yue)的(de)運行(xing)，漠(mo)(mo)大(da)線新建(jian)儲油(you)罐(guan)(guan)已儲油(you)近(jin)4萬立方米(mi)。漠(mo)(mo)大(da)線適(shi)應(ying)性(xing)改(gai)(gai)(gai)造(zao)(zao)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)的(de)完(wan)(wan)成(cheng)(cheng)，有(you)效緩解事故(gu)應(ying)急處(chu)置時(shi)間上的(de)壓力，削(xue)減了漠(mo)(mo)河首(shou)站(zhan)高(gao)罐(guan)(guan)位運行(xing)風險(xian)。
