Spirit Energy在巴倫支海進行鉆探

據(jù)油田技術(shù)7月6日報道，擁有719生產(chǎn)許可證的挪威Spirit Energy AS已經(jīng)完成了對7321/8-2 S號油井的鉆探工作。該井在Johan Castberg油田以北110 千米處和Hammerfest以北約310 千米處鉆探。

在第一次勘探中，該井遇到厚度約30米的St?組，含水砂巖層20 米，主要儲層質(zhì)量中等。Fruholmen組厚約120米，上部有多個含水砂巖層，共30米，儲層質(zhì)量中、差水平為主。在Snadd地層上部約80 米處鉆井，僅遇到厚2 米的含水砂巖層，儲層質(zhì)量良好。

二次勘探目標在下白堊統(tǒng)（Kolje組）的淤泥和細砂中發(fā)現(xiàn)了石油的蹤跡。這口井被歸為干井。

Spirit Energy drills dry well in Barents Sea

Spirit Energy Norway AS, operator of production licence 719, has concluded the drilling of wildcat well 7321/8-2 S.

The well was drilled about 110 km north of the Johan Castberg field and about 310 km north of Hammerfest.

In the primary exploration target, the well encountered the St? Formation with a thickness of about 30 m, with water-bearing sandstone layers of 20 m, mainly with moderate reservoir quality. The Fruholmen Formation was about 120 m thick, with several water-bearing sandstone layers in the upper part of the formation, totalling 30 m, mainly with moderate to poor reservoir quality.

About 80 m of the upper part of the Snadd Formation was drilled, but the only thing encountered was a water-bearing sandstone layer, 2 m thick and with good reservoir quality.

The secondary exploration target encountered traces of petroleum in silt/fine sands in the Lower Cretaceous (the Kolje Formation). The well is classified as dry.
