美頁巖油生產效率持續提高

根(gen)據EIA的《鉆(zhan)井(jing)產能(neng)報告》，2007年以(yi)來的10年，美國主要頁(ye)巖(yan)(yan)區(qu)新鉆(zhan)井(jing)的首月(yue)產量呈持續(xu)增(zeng)長之勢，在油價下跌期間亦如此。得益于壓裂作業中注入(ru)更多支撐劑、增(zeng)加(jia)水平(ping)段長度等措施，二(er)疊紀盆地(di)頁(ye)巖(yan)(yan)油井(jing)的首月(yue)初(chu)始產量已由(you)(you)2013年的不到100桶(tong)(tong)(tong)(tong)/日(ri)增(zeng)至500桶(tong)(tong)(tong)(tong)/日(ri)，鷹灘(tan)頁(ye)巖(yan)(yan)區(qu)由(you)(you)不到200桶(tong)(tong)(tong)(tong)/日(ri)增(zeng)至600桶(tong)(tong)(tong)(tong)/日(ri)以(yi)上，巴肯頁(ye)巖(yan)(yan)區(qu)由(you)(you)近300桶(tong)(tong)(tong)(tong)/日(ri)增(zeng)至近700桶(tong)(tong)(tong)(tong)/日(ri)，奈厄布(bu)拉勒頁(ye)巖(yan)(yan)區(qu)由(you)(you)50桶(tong)(tong)(tong)(tong)/日(ri)增(zeng)至200桶(tong)(tong)(tong)(tong)/日(ri)以(yi)上，阿納(na)達(da)科盆地(di)由(you)(you)100桶(tong)(tong)(tong)(tong)/日(ri)左右增(zeng)至近300桶(tong)(tong)(tong)(tong)/日(ri)。

持續增(zeng)加的新井產(chan)(chan)能(neng)支(zhi)撐美國頁巖(yan)油產(chan)(chan)量在2015年(nian)油價(jia)大幅下(xia)滑(hua)和作業量大幅減少的情況(kuang)下(xia)，仍保持了(le)增(zeng)長；2016年(nian)在油價(jia)和鉆機數量進一步下(xia)滑(hua)的情況(kuang)下(xia)，頁巖(yan)油產(chan)(chan)量也僅出現小幅下(xia)降。
