5月(yue)5日，由中國石(shi)油化工集團公司勝利西南石(shi)油工程管理中心70597鉆(zhan)(zhan)井(jing)隊承鉆(zhan)(zhan)的(de)普(pu)光105-2井(jing)順(shun)利完(wan)鉆(zhan)(zhan)。至此，普(pu)光氣田主(zhu)體鉆(zhan)(zhan)井(jing)工程宣布(bu)結束，39口(kou)開發井(jing)全部(bu)進入投(tou)產準備階段，已完(wan)成試氣作業的(de)20口(kou)井(jing)均獲得高產工業氣流。
普光氣田(tian)主(zhu)體共(gong)探明天然氣儲(chu)量(liang)2782.9億(yi)立方米，計劃(hua)動用(yong)儲(chu)量(liang)1811.1億(yi)立方米，共(gong)在18個平臺上部署開(kai)發井(jing)39口，以確保年105億(yi)立方米混合天然氣的生產能力(li)。2005年12月8日，普光302-1井(jing)開(kai)鉆，標志著開(kai)發鉆井(jing)生產正式(shi)拉開(kai)序(xu)幕。
普光(guang)氣(qi)田天然氣(qi)儲層埋藏(zang)深，且高溫、高壓、高含硫，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)生(sheng)產(chan)始終要(yao)(yao)面(mian)對“噴、漏、卡、塌”等世界級難題(ti)，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)施(shi)工(gong)(gong)(gong)周期長、風(feng)險大(da)。為(wei)加快開發井(jing)(jing)(jing)(jing)建設(she)速(su)度，川氣(qi)東送建設(she)工(gong)(gong)(gong)程(cheng)(cheng)指揮部(bu)與(yu)參建單位(wei)一起，圍(wei)繞(rao)制(zhi)約鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)生(sheng)產(chan)的(de)(de)(de)各類復雜問題(ti)開展科技(ji)攻關，加大(da)新(xin)技(ji)術(shu)、新(xin)工(gong)(gong)(gong)藝(yi)的(de)(de)(de)推廣應(ying)用力度，先后確定了(le)多項鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)先導試驗項目，成(cheng)功將氣(qi)體鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)、垂直鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)、鉆(zhan)(zhan)(zhan)(zhan)頭優選、復合鉆(zhan)(zhan)(zhan)(zhan)進(jin)等一批(pi)最新(xin)技(ji)術(shu)成(cheng)果應(ying)用于鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)生(sheng)產(chan)。在上部(bu)陸相地(di)層，大(da)力推廣氣(qi)體鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)技(ji)術(shu)，在下部(bu)海相地(di)層則應(ying)用高效PDC鉆(zhan)(zhan)(zhan)(zhan)頭+螺桿復合鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)技(ji)術(shu)，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)速(su)度大(da)大(da)加快，平均機械鉆(zhan)(zhan)(zhan)(zhan)速(su)提(ti)高3～8倍。承擔開發鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)施(shi)工(gong)(gong)(gong)任務的(de)(de)(de)中原(yuan)、勝(sheng)利等鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)隊(dui)，圍(wei)繞(rao)“抓管理、強(qiang)(qiang)素質，降事故、提(ti)水平”的(de)(de)(de)要(yao)(yao)求，在堅持(chi)安(an)全生(sheng)產(chan)的(de)(de)(de)前提(ti)下，加強(qiang)(qiang)對生(sheng)產(chan)過程(cheng)(cheng)的(de)(de)(de)控(kong)制(zhi)，注重生(sheng)產(chan)細節，超(chao)(chao)前計劃、超(chao)(chao)前準備(bei)，搞(gao)好鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)施(shi)工(gong)(gong)(gong)中的(de)(de)(de)工(gong)(gong)(gong)序銜接，減(jian)少(shao)了(le)各類事故的(de)(de)(de)發生(sheng)，提(ti)高了(le)鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)生(sheng)產(chan)時效。
據統計(ji)，普光氣田39口開(kai)發井(jing)(jing)累計(ji)鉆(zhan)(zhan)井(jing)(jing)進尺23.4841萬米，合計(ji)鉆(zhan)(zhan)井(jing)(jing)時(shi)間22.14萬小時(shi)，平均鉆(zhan)(zhan)井(jing)(jing)周(zhou)期(qi)175.96天，與同區塊勘探鉆(zhan)(zhan)井(jing)(jing)周(zhou)期(qi)相比，減少了(le)156.83天。普光202-1井(jing)(jing)更是創出(chu)了(le)鉆(zhan)(zhan)井(jing)(jing)周(zhou)期(qi)108天、建井(jing)(jing)周(zhou)期(qi)134天的川東北最好紀(ji)錄(lu)。
