中国石化新闻网讯 据彭博社莫斯科1月10日报道，俄罗斯天然气工业股份公司(Gazprom Neft )的子公司俄气石油亚马尔公司在其波尔托夫斯科耶油田(Novoportovskoye field)完成了俄罗斯首个有四个水平的套管井侧轨道的多侧井的施工。 共钻了6,756米，包括在目的层钻的4411米。 这口井在39天内以每1000米5.78天的速度被建造起来。 水平分枝井的钻井有利于从不连通的低渗透层地层中大量增加排水量，显著地增加了生产层的采收率，使边际储量得以开发，而不必再钻额外的井。 油井建设中根据波尔托夫斯科耶油田(Novoportovskoye field)的具体地质条件使用并重新调整了俄罗斯生产的设备。 蔡小全 编译自 彭博社 原文如下： Gazprom Neft drills first-ever multi-lateral well in Russia Gazprom Neft subsidiary Gazpromneft-Yamal has completed construction of Russia’s first-ever multi-lateral well with four horizontal cased-hole side tracks, at its Novoportovskoye field. A total 6,756 m was drilled, including 4,411 m drilled in the target strata. The well was constructed in 39 days at a rate of 5.78 days per 1,000 m. Drilling horizontally branched wells facilitates a manifold increase in drainage from disjointed low-permeability strata, significantly increasing the oil recovery factor at productive strata and bringing marginal reserves into development without the need to drill additional wells. Russian-produced equipment was used in well construction, retooled in line with the specific geological conditions of Novoportovskoye field. |
