5月5日，由中(zhong)國石油化工(gong)(gong)集團公司勝利西南石油工(gong)(gong)程管(guan)理中(zhong)心70597鉆井(jing)(jing)(jing)隊承鉆的普(pu)光105-2井(jing)(jing)(jing)順(shun)利完鉆。至(zhi)此，普(pu)光氣田主(zhu)體鉆井(jing)(jing)(jing)工(gong)(gong)程宣布結束(shu)，39口(kou)開發井(jing)(jing)(jing)全部進入投產(chan)準備階段，已完成試氣作業的20口(kou)井(jing)(jing)(jing)均獲得高產(chan)工(gong)(gong)業氣流。
普(pu)光氣(qi)田主體共(gong)(gong)探明天然(ran)氣(qi)儲(chu)量(liang)2782.9億(yi)立方米(mi)，計劃動用儲(chu)量(liang)1811.1億(yi)立方米(mi)，共(gong)(gong)在18個平臺上部署開發(fa)井(jing)(jing)(jing)39口，以確保年(nian)105億(yi)立方米(mi)混合天然(ran)氣(qi)的生產能(neng)力。2005年(nian)12月8日，普(pu)光302-1井(jing)(jing)(jing)開鉆(zhan)，標志著開發(fa)鉆(zhan)井(jing)(jing)(jing)生產正式拉開序幕。
普光(guang)氣(qi)田(tian)天然(ran)氣(qi)儲層(ceng)埋藏深，且(qie)高溫、高壓(ya)、高含硫，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)始終要面(mian)對“噴、漏、卡、塌”等世界(jie)級難(nan)題，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)施(shi)(shi)工周期長、風險大(da)(da)。為加快(kuai)開發(fa)井(jing)(jing)(jing)(jing)建設(she)速度，川氣(qi)東送建設(she)工程(cheng)指揮(hui)部與(yu)參(can)建單位一(yi)起，圍(wei)繞(rao)制約(yue)鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)各(ge)類復(fu)雜(za)問題開展科(ke)技(ji)(ji)攻關，加大(da)(da)新技(ji)(ji)術(shu)(shu)、新工藝的(de)推廣應(ying)用力度，先后確(que)定了多項鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)先導(dao)試驗項目，成功將氣(qi)體(ti)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(you)選、復(fu)合鉆(zhan)(zhan)(zhan)(zhan)進(jin)等一(yi)批最(zui)新技(ji)(ji)術(shu)(shu)成果應(ying)用于(yu)鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)。在上部陸(lu)相地層(ceng)，大(da)(da)力推廣氣(qi)體(ti)鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)技(ji)(ji)術(shu)(shu)，在下部海相地層(ceng)則應(ying)用高效PDC鉆(zhan)(zhan)(zhan)(zhan)頭+螺桿復(fu)合鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)技(ji)(ji)術(shu)(shu)，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)速度大(da)(da)大(da)(da)加快(kuai)，平(ping)均機械鉆(zhan)(zhan)(zhan)(zhan)速提(ti)高3～8倍。承擔開發(fa)鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)施(shi)(shi)工任務的(de)中(zhong)原、勝利等鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)隊，圍(wei)繞(rao)“抓管理(li)、強素(su)質，降事(shi)故、提(ti)水(shui)平(ping)”的(de)要求，在堅(jian)持安全(quan)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)前提(ti)下，加強對生(sheng)(sheng)(sheng)產(chan)(chan)(chan)過程(cheng)的(de)控制，注重生(sheng)(sheng)(sheng)產(chan)(chan)(chan)細節，超前計(ji)劃、超前準備，搞好鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)施(shi)(shi)工中(zhong)的(de)工序銜接，減少(shao)了各(ge)類事(shi)故的(de)發(fa)生(sheng)(sheng)(sheng)，提(ti)高了鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)(jing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)時效。
據統計，普(pu)光氣田(tian)39口開(kai)發(fa)井(jing)累(lei)計鉆(zhan)井(jing)進尺23.4841萬(wan)米，合計鉆(zhan)井(jing)時間22.14萬(wan)小時，平均(jun)鉆(zhan)井(jing)周期(qi)175.96天(tian)(tian)，與同區塊勘探鉆(zhan)井(jing)周期(qi)相(xiang)比，減(jian)少了156.83天(tian)(tian)。普(pu)光202-1井(jing)更是創出了鉆(zhan)井(jing)周期(qi)108天(tian)(tian)、建井(jing)周期(qi)134天(tian)(tian)的川東北(bei)最好紀錄。
