上半年，在海上油田低產低效井治理中，中國石化勝利油田海洋采油廠大力實施作業油層保護一體化和油藏工藝一體化，提高作業有效率，完成油水井作業48口，累計增油4.23萬噸。
這個廠(chang)實施(shi)(shi)以(yi)油(you)層(ceng)(ceng)保護(hu)為中心的作業設計(ji)、施(shi)(shi)工(gong)(gong)、監督(du)一體(ti)化運(yun)行，對(dui)因結(jie)垢(gou)、地(di)層(ceng)(ceng)堵塞和注(zhu)采井(jing)(jing)網不完(wan)善(shan)(shan)等造(zao)成的低(di)產(chan)(chan)(chan)(chan)低(di)效井(jing)(jing)，在制定方案(an)措施(shi)(shi)時突出油(you)藏工(gong)(gong)藝結(jie)合(he)，開展油(you)藏工(gong)(gong)藝一體(ti)化綜合(he)治(zhi)理。CB11NB-4井(jing)(jing)在生產(chan)(chan)(chan)(chan)過程中日產(chan)(chan)(chan)(chan)液量緩(huan)慢下降，日產(chan)(chan)(chan)(chan)油(you)僅為9.3噸(dun)(dun)。技術人(ren)員分(fen)析發現該井(jing)(jing)低(di)產(chan)(chan)(chan)(chan)是(shi)因長期生產(chan)(chan)(chan)(chan)造(zao)成近井(jing)(jing)地(di)帶堵塞。4月，他(ta)們對(dui)該井(jing)(jing)實施(shi)(shi)酸(suan)化解堵和生產(chan)(chan)(chan)(chan)參數調整，日產(chan)(chan)(chan)(chan)液從20.3噸(dun)(dun)上(shang)升(sheng)(sheng)到123.5噸(dun)(dun)，日產(chan)(chan)(chan)(chan)油(you)上(shang)升(sheng)(sheng)到18.3噸(dun)(dun)。針對(dui)注(zhu)采不完(wan)善(shan)(shan)造(zao)成的油(you)井(jing)(jing)低(di)產(chan)(chan)(chan)(chan)和高(gao)含水問題(ti)，該廠(chang)加快注(zhu)水井(jing)(jing)投轉注(zhu)及歸位施(shi)(shi)工(gong)(gong)，完(wan)善(shan)(shan)注(zhu)采井(jing)(jing)網，合(he)理分(fen)層(ceng)(ceng)注(zhu)采調配，改善(shan)(shan)分(fen)層(ceng)(ceng)吸水狀況(kuang)，提升(sheng)(sheng)地(di)層(ceng)(ceng)壓力，使注(zhu)采對(dui)應率提高(gao)了1%。
