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)決漠河首(shou)(shou)站(zhan)高罐(guan)(guan)(guan)位(wei)運(yun)(yun)行(xing)風險(xian)，2012年(nian)(nian)5月10日，漠大(da)線適(shi)(shi)(shi)應(ying)性改(gai)造(zao)(zao)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)正式啟動。面對大(da)興安(an)嶺地區(qu)僅有4個(ge)月施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)作業時(shi)間(jian)的實際，工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)建(jian)(jian)設者(zhe)(zhe)分(fen)秒必爭，倒排工(gong)(gong)(gong)(gong)(gong)(gong)期節(jie)點，清(qing)晰劃分(fen)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)作業面，僅用40天完(wan)(wan)成(cheng)(cheng)5000多噸的罐(guan)(guan)(guan)板(ban)運(yun)(yun)輸任務，45天完(wan)(wan)成(cheng)(cheng)14萬(wan)立方(fang)米土石挖填及儲(chu)罐(guan)(guan)(guan)基礎(chu)工(gong)(gong)(gong)(gong)(gong)(gong)作，37天完(wan)(wan)成(cheng)(cheng)儲(chu)油(you)罐(guan)(guan)(guan)主體安(an)裝工(gong)(gong)(gong)(gong)(gong)(gong)作。去年(nian)(nian)10月15日，漠大(da)線適(shi)(shi)(shi)應(ying)性改(gai)造(zao)(zao)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)4個(ge)儲(chu)油(you)罐(guan)(guan)(guan)完(wan)(wan)成(cheng)(cheng)上(shang)水(shui)沉降試驗(yan)，10月25日，漠河首(shou)(shou)站(zhan)新建(jian)(jian)罐(guan)(guan)(guan)區(qu)工(gong)(gong)(gong)(gong)(gong)(gong)藝管(guan)網最后一道焊口焊接完(wan)(wan)畢(bi)，標志著漠河首(shou)(shou)站(zhan)新老罐(guan)(guan)(guan)區(qu)工(gong)(gong)(gong)(gong)(gong)(gong)藝管(guan)網具備連(lian)通條件。今年(nian)(nian)春季(ji)，經(jing)(jing)過建(jian)(jian)設者(zhe)(zhe)緊鑼(luo)密鼓的施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)，漠大(da)線場區(qu)配(pei)套工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)相(xiang)繼完(wan)(wan)成(cheng)(cheng)。7月9日，漠大(da)線適(shi)(shi)(shi)應(ying)性改(gai)造(zao)(zao)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)順利竣工(gong)(gong)(gong)(gong)(gong)(gong)投產(chan)。 經(jing)(jing)過兩(liang)個(ge)月的運(yun)(yun)行(xing)，漠大(da)線新建(jian)(jian)儲(chu)油(you)罐(guan)(guan)(guan)已儲(chu)油(you)近(jin)4萬(wan)立方(fang)米。漠大(da)線適(shi)(shi)(shi)應(ying)性改(gai)造(zao)(zao)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)的完(wan)(wan)成(cheng)(cheng)，有效緩解(jie)事故應(ying)急處置時(shi)間(jian)上(shang)的壓力，削減(jian)了(le)漠河首(shou)(shou)站(zhan)高罐(guan)(guan)(guan)位(wei)運(yun)(yun)行(xing)風險(xian)。
