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(jie)決漠(mo)(mo)河(he)首站高罐位運(yun)行風險，2012年5月(yue)(yue)10日(ri)，漠(mo)(mo)大(da)線(xian)適應(ying)(ying)性改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)(gong)程(cheng)正式啟動。面對(dui)大(da)興安嶺地(di)區(qu)僅有4個月(yue)(yue)施(shi)工(gong)(gong)(gong)(gong)作(zuo)業時間的(de)實際，工(gong)(gong)(gong)(gong)程(cheng)建(jian)設者分秒(miao)必爭，倒排工(gong)(gong)(gong)(gong)期節點，清晰劃分施(shi)工(gong)(gong)(gong)(gong)作(zuo)業面，僅用40天(tian)完(wan)成(cheng)(cheng)5000多噸的(de)罐板(ban)運(yun)輸任(ren)務，45天(tian)完(wan)成(cheng)(cheng)14萬立方(fang)米(mi)土石挖填(tian)及儲(chu)(chu)(chu)罐基礎(chu)工(gong)(gong)(gong)(gong)作(zuo)，37天(tian)完(wan)成(cheng)(cheng)儲(chu)(chu)(chu)油(you)(you)罐主體安裝工(gong)(gong)(gong)(gong)作(zuo)。去年10月(yue)(yue)15日(ri)，漠(mo)(mo)大(da)線(xian)適應(ying)(ying)性改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)(gong)程(cheng)4個儲(chu)(chu)(chu)油(you)(you)罐完(wan)成(cheng)(cheng)上(shang)水沉(chen)降試驗，10月(yue)(yue)25日(ri)，漠(mo)(mo)河(he)首站新建(jian)罐區(qu)工(gong)(gong)(gong)(gong)藝管網最后一道焊(han)口焊(han)接完(wan)畢，標志著漠(mo)(mo)河(he)首站新老罐區(qu)工(gong)(gong)(gong)(gong)藝管網具備連通條(tiao)件。今年春(chun)季，經(jing)過(guo)建(jian)設者緊鑼(luo)密鼓(gu)的(de)施(shi)工(gong)(gong)(gong)(gong)，漠(mo)(mo)大(da)線(xian)場區(qu)配套工(gong)(gong)(gong)(gong)程(cheng)相(xiang)繼完(wan)成(cheng)(cheng)。7月(yue)(yue)9日(ri)，漠(mo)(mo)大(da)線(xian)適應(ying)(ying)性改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)(gong)程(cheng)順利(li)竣工(gong)(gong)(gong)(gong)投產。 經(jing)過(guo)兩個月(yue)(yue)的(de)運(yun)行，漠(mo)(mo)大(da)線(xian)新建(jian)儲(chu)(chu)(chu)油(you)(you)罐已儲(chu)(chu)(chu)油(you)(you)近4萬立方(fang)米(mi)。漠(mo)(mo)大(da)線(xian)適應(ying)(ying)性改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)(gong)程(cheng)的(de)完(wan)成(cheng)(cheng)，有效緩解(jie)事(shi)故應(ying)(ying)急處置時間上(shang)的(de)壓力(li)，削減(jian)了漠(mo)(mo)河(he)首站高罐位運(yun)行風險。
