截至8月中旬，中國中化集團公司（簡稱中化集團）下屬企業中化石油勘探開發公司擁有40%非作業者權益的Oudna油田已完成全年產量任務，比原定計劃提前近4個月。預計Oudna油田全年將為中化生產權益油49萬桶，為年初計劃的149%，超計劃產油15萬桶。
Oudna油(you)(you)(you)田(tian)(tian)(tian)(tian)位于(yu)突(tu)尼斯海上，屬于(yu)邊際斷塊油(you)(you)(you)田(tian)(tian)(tian)(tian)。油(you)(you)(you)田(tian)(tian)(tian)(tian)開(kai)發應用了多(duo)項世(shi)界(jie)領先(xian)技(ji)術，如使用世(shi)界(jie)上最(zui)大(da)排(pai)量(liang)的(de)(de)射流泵生產(chan)(chan)、使用最(zui)先(xian)進的(de)(de)膨脹防砂篩管ESS(Expandable Sand Screen)等(deng)。油(you)(you)(you)田(tian)(tian)(tian)(tian)投產(chan)(chan)9個月(yue)后收回(hui)開(kai)發投資(zi)，單井最(zui)高日(ri)產(chan)(chan)油(you)(you)(you)量(liang)超過(guo)25,000桶(tong)(tong)。但從(cong)2007年(nian)底開(kai)始，油(you)(you)(you)田(tian)(tian)(tian)(tian)大(da)量(liang)出砂，含水(shui)快(kuai)速上升，產(chan)(chan)量(liang)大(da)幅降(jiang)低，由日(ri)產(chan)(chan)超過(guo)20,000桶(tong)(tong)水(shui)平降(jiang)至(zhi)不(bu)足5,000桶(tong)(tong)，產(chan)(chan)量(liang)形勢十分嚴(yan)峻。一(yi)(yi)年(nian)多(duo)來，勘探(tan)開(kai)發公(gong)司(si)一(yi)(yi)手(shou)抓(zhua)技(ji)術研究，一(yi)(yi)手(shou)抓(zhua)項目管理(li)，通過(guo)調整油(you)(you)(you)田(tian)(tian)(tian)(tian)生產(chan)(chan)動態(tai)，有效減緩了油(you)(you)(you)田(tian)(tian)(tian)(tian)含水(shui)的(de)(de)快(kuai)速上升，同時提高油(you)(you)(you)田(tian)(tian)(tian)(tian)產(chan)(chan)液量(liang)，加(jia)快(kuai)了油(you)(you)(you)田(tian)(tian)(tian)(tian)的(de)(de)開(kai)采(cai)速度(du)，提前(qian)4個月(yue)完成2009年(nian)全年(nian)產(chan)(chan)量(liang)任務。截至(zhi)目前(qian)，油(you)(you)(you)田(tian)(tian)(tian)(tian)穩產(chan)(chan)時間(4,000~3,500桶(tong)(tong)/日(ri))已(yi)經(jing)連續(xu)超過(guo)15個月(yue)，油(you)(you)(you)田(tian)(tian)(tian)(tian)單井累計產(chan)(chan)油(you)(you)(you)量(liang)已(yi)經(jing)超過(guo)860萬桶(tong)(tong)，進一(yi)(yi)步提高了項目的(de)(de)資(zi)產(chan)(chan)價值。
