5月5日，由中(zhong)國石油化工(gong)(gong)(gong)集團公司勝利(li)西南石油工(gong)(gong)(gong)程管(guan)理中(zhong)心70597鉆(zhan)(zhan)井(jing)隊(dui)承鉆(zhan)(zhan)的(de)普光105-2井(jing)順利(li)完鉆(zhan)(zhan)。至此，普光氣(qi)(qi)田主體(ti)鉆(zhan)(zhan)井(jing)工(gong)(gong)(gong)程宣(xuan)布結束，39口(kou)(kou)開發井(jing)全部進入投產準備(bei)階(jie)段(duan)，已完成(cheng)試氣(qi)(qi)作業的(de)20口(kou)(kou)井(jing)均獲得高產工(gong)(gong)(gong)業氣(qi)(qi)流。
普光氣(qi)田主(zhu)體共(gong)(gong)探明天然氣(qi)儲量2782.9億立(li)方米(mi)(mi)，計劃動用儲量1811.1億立(li)方米(mi)(mi)，共(gong)(gong)在18個平臺上部署開(kai)發井(jing)(jing)39口，以確保(bao)年105億立(li)方米(mi)(mi)混合天然氣(qi)的(de)生產(chan)能力。2005年12月8日，普光302-1井(jing)(jing)開(kai)鉆(zhan)，標(biao)志(zhi)著開(kai)發鉆(zhan)井(jing)(jing)生產(chan)正式拉開(kai)序幕。
普光氣田天然氣儲層(ceng)(ceng)埋藏深，且(qie)高(gao)(gao)溫、高(gao)(gao)壓、高(gao)(gao)含硫，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)生產始(shi)終要(yao)(yao)面對(dui)“噴、漏、卡、塌”等世(shi)界級(ji)難(nan)題(ti)，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)施(shi)工(gong)周期長、風(feng)險大。為加(jia)快開(kai)發井(jing)(jing)(jing)建設速(su)(su)度(du)，川氣東送建設工(gong)程指揮部(bu)與參建單位(wei)一起，圍繞制(zhi)約鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)生產的(de)(de)(de)各(ge)類(lei)復(fu)雜問(wen)題(ti)開(kai)展科技攻關，加(jia)大新(xin)技術(shu)、新(xin)工(gong)藝的(de)(de)(de)推(tui)廣應用力(li)度(du)，先(xian)后(hou)確定了多項鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)先(xian)導試驗項目，成(cheng)功將氣體鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)、垂直鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)、鉆(zhan)(zhan)(zhan)(zhan)頭優選、復(fu)合鉆(zhan)(zhan)(zhan)(zhan)進等一批最新(xin)技術(shu)成(cheng)果應用于鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)生產。在上部(bu)陸相(xiang)地層(ceng)(ceng)，大力(li)推(tui)廣氣體鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)技術(shu)，在下部(bu)海相(xiang)地層(ceng)(ceng)則應用高(gao)(gao)效PDC鉆(zhan)(zhan)(zhan)(zhan)頭+螺桿復(fu)合鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)技術(shu)，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)速(su)(su)度(du)大大加(jia)快，平(ping)均機(ji)械鉆(zhan)(zhan)(zhan)(zhan)速(su)(su)提高(gao)(gao)3～8倍。承擔開(kai)發鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)施(shi)工(gong)任務的(de)(de)(de)中(zhong)原、勝(sheng)利等鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)隊，圍繞“抓管(guan)理、強(qiang)素質，降事故、提水平(ping)”的(de)(de)(de)要(yao)(yao)求，在堅持安全生產的(de)(de)(de)前(qian)提下，加(jia)強(qiang)對(dui)生產過程的(de)(de)(de)控(kong)制(zhi)，注重生產細(xi)節(jie)，超前(qian)計劃、超前(qian)準備，搞(gao)好鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)施(shi)工(gong)中(zhong)的(de)(de)(de)工(gong)序銜接，減少了各(ge)類(lei)事故的(de)(de)(de)發生，提高(gao)(gao)了鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)(jing)生產時效。
據統(tong)計，普光氣田39口開(kai)發(fa)井(jing)累計鉆(zhan)(zhan)井(jing)進尺23.4841萬米，合計鉆(zhan)(zhan)井(jing)時間22.14萬小(xiao)時，平均鉆(zhan)(zhan)井(jing)周(zhou)期175.96天，與同區塊勘(kan)探(tan)鉆(zhan)(zhan)井(jing)周(zhou)期相比，減少(shao)了156.83天。普光202-1井(jing)更(geng)是(shi)創出了鉆(zhan)(zhan)井(jing)周(zhou)期108天、建井(jing)周(zhou)期134天的(de)川東北最好紀錄。
