5月5日，由中(zhong)國石(shi)油化工集(ji)團公(gong)司勝利西(xi)南石(shi)油工程管理中(zhong)心70597鉆(zhan)井(jing)隊承鉆(zhan)的普光105-2井(jing)順(shun)利完鉆(zhan)。至此，普光氣(qi)田主體鉆(zhan)井(jing)工程宣布(bu)結(jie)束，39口開發(fa)井(jing)全部進入投產(chan)準備階段，已完成試氣(qi)作業的20口井(jing)均獲得(de)高產(chan)工業氣(qi)流。
普光氣田主體共(gong)探明天然氣儲量2782.9億立方(fang)米，計劃動用儲量1811.1億立方(fang)米，共(gong)在(zai)18個平臺上部署(shu)開發(fa)井39口，以確保年105億立方(fang)米混合天然氣的(de)生產能力。2005年12月8日，普光302-1井開鉆(zhan)(zhan)，標(biao)志(zhi)著開發(fa)鉆(zhan)(zhan)井生產正式拉開序幕。
