8月15日，在建立(li)起恒定溫(wen)度場后，中國石油(you)冀東南(nan)堡(bao)(bao)油(you)田首(shou)條海底(di)管道——南(nan)堡(bao)(bao)1-2人(ren)工(gong)島至南(nan)堡(bao)(bao)1-1人(ren)工(gong)島海底(di)管道正(zheng)式投產(chan)。南(nan)堡(bao)(bao)1-2人(ren)工(gong)島上的NP12-X63、NP12-X66、NP12-X67等油(you)井陸續開啟，生產(chan)的原(yuan)油(you)通過海底(di)管道輸送到(dao)南(nan)堡(bao)(bao)油(you)田先導(dao)試驗站處理(li)。
南堡(bao)1-2人工(gong)島至南堡(bao)1-1人工(gong)島海底管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)由(you)(you)1條(tiao)混(hun)輸管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)和1條(tiao)供水(shui)管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)組成，混(hun)輸管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)采(cai)用雙管(guan)(guan)(guan)(guan)(guan)(guan)結(jie)構，外管(guan)(guan)(guan)(guan)(guan)(guan)規格為直(zhi)(zhi)徑(jing)(jing)(jing)660毫(hao)(hao)米，內管(guan)(guan)(guan)(guan)(guan)(guan)規格為直(zhi)(zhi)徑(jing)(jing)(jing)508毫(hao)(hao)米，供水(shui)管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)直(zhi)(zhi)徑(jing)(jing)(jing)356毫(hao)(hao)米，長度均為3.65千米，能(neng)夠滿足(zu)每年100萬噸的(de)原油輸送能(neng)力。海底管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)由(you)(you)中(zhong)國石油海洋工(gong)程設(she)計公(gong)(gong)司設(she)計，執行(xing)國際領先(xian)的(de)挪威船級社(she)標準，采(cai)用分段入海浮拖法鋪設(she)，施工(gong)單位為大港(gang)油建(jian)公(gong)(gong)司，監理單位為勝利監理公(gong)(gong)司，第三方發證檢驗單位是中(zhong)國船級社(she)。
南堡1-2人工(gong)島(dao)至南堡1-1人工(gong)島(dao)海底管道(dao)于(yu)5月(yue)6日開工(gong)建設(she)(she)，8月(yue)13日完成最(zui)后(hou)一道(dao)連頭施工(gong)，期間(jian)受天氣等(deng)因素影(ying)響(xiang)25天，實際有效施工(gong)時(shi)間(jian)74天，較設(she)(she)計施工(gong)周期節約(yue)時(shi)間(jian)50%，為南堡油(you)田1-2人工(gong)島(dao)油(you)井的早日投產爭取了寶貴時(shi)間(jian)。管道(dao)全部貫通后(hou)，根據清管、測徑、試壓等(deng)各種資料和數據顯示，管道(dao)質(zhi)量完全符合設(she)(she)計要求。
據了(le)解，冀東(dong)南(nan)(nan)堡(bao)(bao)油(you)(you)(you)田(tian)(tian)1-2人工(gong)島(dao)(dao)共部署井(jing)位44口，其中油(you)(you)(you)井(jing)27口、水井(jing)17口，目前島(dao)(dao)上有6部鉆機，完井(jing)7口，正鉆井(jing)5口。南(nan)(nan)堡(bao)(bao)1-2人工(gong)島(dao)(dao)至南(nan)(nan)堡(bao)(bao)1-1人工(gong)島(dao)(dao)海(hai)底管道的(de)竣工(gong)投產，為(wei)南(nan)(nan)堡(bao)(bao)油(you)(you)(you)田(tian)(tian)開發(fa)和(he)冀東(dong)油(you)(you)(you)田(tian)(tian)快(kuai)速上產提(ti)供(gong)了(le)重(zhong)要支撐。
