石油圈中國石化新聞網訊 據彭博社莫斯科1月10日報道，俄羅斯天然氣工業股份公司(Gazprom Neft )的子公司俄氣石油亞馬爾公司在其波爾托夫斯科耶油田(Novoportovskoye field)完成了俄羅斯首個有四個水平的套管井側軌道的多側井的施工。 共鉆了6,756米，包括在目的層鉆的4411米。 這口井在39天內以每1000米5.78天的速度被建造起來。 水平分枝井的鉆井有利于從不連通的低滲透層地層中大量增加排水量，顯著地增加了生產層的采收率，使邊際儲量得以開發，而不必再鉆額外的井。 油井建設中根據波爾托夫斯科耶油田(Novoportovskoye field)的具體地質條件使用并重新調整了俄羅斯生產的設備。 蔡小全 編譯自 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.
